OPINION
Before KOELSCH, ELY and WALLACE, Circuit Judges.
ELY, Circuit Judge:
The Moanalua Valley, a beauteous natural wonder that many believe to be of great significance in Hawaiian history,1 lies on Hawaii’s Island of Oahu, directly in the path of a proposed Interstate Highway called H-3. The principal issue on this appeal is whether Moanalua qualifies for protection as an “historic site of State, or local significance” under section [437]*4374(f) of the Department of Transportation Act of 1966, as amended, 49 U.S.C. § 1653(f) (1970), and section 18 of the Federal-Aid Highway Act of 1968, 23 U.S.C. § 138 (1970). (Both statutes, which are essentially identical, are hereinafter referred to simply as “section 4(f)”.2) Relying on a published determination by the Secretary of the Interior that Moanalua is eligible for inclusion in the National Register of Historic Places, the appellants3 contend that section 4(f) applies. The appellees,4 who rely primarily on a determination by Hawaii State officials that Moanalua is only of “marginal” historic significance, argue that section 4(f) is inapplicable to the routing of H-3 through the Valley. Agreeing with the appellees, the District Court dissolved the injunctions that it had previously entered against construction of the highway.5 Stop H-3 Ass’n v. Brinegar, 389 F.Supp. 1102 (D.Hawaii 1974). We reverse.
I. Statutory Background
Public interest in preservation of the physical reminders of our Nation’s past has prompted Congress to implement a strong national policy in favor of historic preservation. See 16 U.S.C. §§ 461, 470; 23 U.S.C. § 138; 49 U.S.C. § 1653(f) (1970). In section 4(f), Congress has determined that historic preservation should be given major consideration in connection with all proposed highway construction programs that are to receive financial aid from the federal government. The statute provides, in declaring national policy, that “ . special effort should be made to preserve . historic sites.” The statute further provides that before the Secretary of Transportation [hereinafter “the Secretary”] may approve the use of Federal funds for a highway that will “use” land from “ . . .an historic site of national, State, or local significance as so determined by [the Federal, State, or local officials having jurisdiction thereof],” he must determine that no “feasible and prudent” alternative route exists. If there is no “feasible and prudent” alternative, the Secretary may approve the project only if there has been “ . . . all possible [438]*438planning to minimize harm . . . ” to the historic site. See Citizens to Preserve Overton Park, Inc. v. Volpe, 401 U.S. 402, 411-18, 91 S.Ct. 814, 821, 28 L.Ed.2d 136, 150 (1971). The requirements are stringent. Congress clearly reflected its intent that there shall no longer be reckless, ill-considered, wanton desecration of natural sites significantly related to our country’s heritage.
As one step toward implementing the national policy in furtherance of historic preservation, Congress, in the National Historic Preservation Act of 1966 [hereinafter “the NHPA”], 16 U.S.C. §§ 470 et seq. (1970), authorized the Secretary of the Interior
to expand and maintain a national register of districts, sites, buildings, structures, and objects significant in American history, architecture, archeology, and culture, hereinafter referred to as the National Register .
16 U.S.C. § 470a(a)(l) (1970). The National Register, which includes properties of State and local, as well as national, historic significance, is intended to provide a “ . convenient guide to properties which should be preserved . . . H.R.Rep.No.1916, 89th Cong., 2d Sess., reproduced at 1966 U.S.Code Cong. & Admin.News pp. 3307, 3310. In the NHPA, Congress also created the Advisory Council on Historic Preservation [hereinafter “the Advisory Council”], which is composed of the head officials of certain Federal agencies and other persons, appointed by the President, who have experience and interests in the field of historic preservation. 16 U.S.C. § 470i (1970). The Advisory Council is responsible for coordinating the historic preservation efforts of Federal agencies, state governments, and other organizations, and for making recommendations on matters pertaining to the protection and preservation of historic sites. 16 U.S.C. § 470j (1970).
To facilitate the identification of properties of State and local historic significance that qualify for inclusion in the National Register, the Secretary of the Interior has established certain “National Register Criteria.” These Criteria broadly provide, in pertinent part, as follows:
The quality of significance in American history, architecture, archeology, and culture is present in districts, sites, buildings, structures, and objects of State and local importance that possess integrity of location, design, setting, materials, workmanship, feeling and association and:
(1) That are associated with events that have made a significant contribution to the broad patterns of our history; or
(2) That are associated with the lives of persons significant in our past; or
(3) That embody the distinctive characteristics of a type, period, or method of construction, or that represent the work of a master, or that possess high artistic values, or that represent a significant and distinguishable entity whose components may lack individual distinction; or
(4) That have yielded, or may be likely to yield, information important in prehistory or history.
36 C.F.R. § 800.10 (1975).
As defined in 36 C.F.R. § 800.3(f) (1975), the phrase “property eligible for inclusion in the National Register” means “any district, site, building, structure, or object which the Secretary of the Interior determines is likely to meet the National Register Criteria.” For the purposes of NHPA, the regulations place property that is eligible for inclusion in the National Register on an equal footing with property that is actually listed in the Register. See 36 C.F.R. §§ 800.4(a)-(b) (1975).
II. The Factual Setting
As planned, H-3 would constitute the third and final segment of Hawaii’s Interstate Highway System. It would be a six-lane, controlled-access highway extending for approximately fifteen miles across the southern half of Oahu, from near Pearl Harbor, on the Island’s leeward side, across the Koolau Mountains, to the Kaneohe Marine Corps Air Station, on the windward side. Two conventional highways, the Pali and Likelike Highways, now provide transKoolau routes, but according to some offi[439]*439cial projections, these highways will soon be inadequate to serve the growing population on Oahu’s windward side. The Moanalua Valley, which is privately owned, lies within Oahu’s interior. H-3’s projected route extends for approximately three miles along Moanalua’s narrow floor. Within Moanalua, H-3 would pass from within 100 to 200 feet of a large petroglyph rock that is known as Pohaku ka Luahine.6
In March, 1973, the Moanalua Gardens Foundation, a private, non-profit organization that is interested in Moanalua’s preservation, nominated both the Valley and Pohaku ka Luahine for inclusion in the National Register. On July 23,1973, the Interior Secretary named Pohaku ka Luahine to the National Register. 39 Fed.Reg. 6402, 6422 (1974). In October of 1973, the Interi- or Secretary’s Advisory Board on National Parks, Historic Sites, Buildings and Monuments considered the historic significance of Moanalua Valley. The Board noted that much of the information concerning Moanalua’s importance existed only within the private notebooks of oral traditions about the Valley that had been kept by the Valley’s former owner, Gertrude Damon, and that since the Damon notebooks had never been released by the Damon estate, they had never been subjected to rigorous scrutiny. Consequently, while the Board believed that Moanalua had not been conclusively demonstrated to be of national historic significance, it concluded that “[hjistorical, cultural, and natural values combined with outstanding potential for an environmental study area endow Moanalua Valley with an importance that makes its preservation clearly in the public interest.”7
On May 8, 1974, the Interior Secretary published a Notice in the Federal Register that Moanalua, along with a number of other properties,
may be eligible for inclusion in the National Register of Historic Places and are therefore entitled to protection under section 1(3) and section 2(b) of Executive Order 11593 and other applicable Federal legislation.
39 Fed.Reg. 16175-76 (1974).8 Explaining his decision, then Interior Secretary Morton wrote in a letter to the Governor of Hawaii that while Moanalua was not of national historic significance, the Valley “possessed historical and cultural values of at least local dimensions and, therefore, could meet the less stringent criteria of the National Register for sites of local significance.”9
Thereafter, however, on August 5, 1974, the Hawaii Historic Places Review Board, a State body responsible for evaluating and nominating Hawaiian properties for inclusion in the National Register and for maintaining the Hawaii Register of Historic [440]*440Places,10 met concerning Moanalua and determined that the Valley was only of “marginal” local significance,11 a classification that affords the Valley no protection from destruction.
Since Pohaku ka Luahine had already been named to the National Register, the Federal Highway Administrator, in compliance with 36 C.F.R. § 800.4 (1975), requested the Advisory Council on Historic Preservation to comment concerning H-3’s potential impact on the petroglyph rock. The Advisory Council met on August 6th and 7th, 1974. Because the Interior Secretary had recently determined that Moanalua was eligible for inclusion in the National Register, the Council broadened its review of H-3 from that requested by the Federal Highway Administrator to include the highway’s potential impact on the Valley. The Advisory Council’s report, copies of which were furnished to the Secretary of Transportation and to the Secretary of the Interi- or, concluded that both Pohaku ka Luahine and the Moanalua Valley possessed “historical, cultural, and archeological significance warranting their preservation.”
Notwithstanding the Advisory Council’s report and the Interior Secretary’s published determination that Moanalua “may be eligible” for inclusion in the National Register, the Secretary of Transportation concluded, in September of 1974, that “. the Valley does not come under the provisions of Section 4(f).”12
III. Discussion
The District Court did not dispute the significance attached by the regulations to property that is eligible for inclusion in the National Register. The court wrote:
[Djetermination by the secretary of interior that a property is eligible for inclusion in the National Register triggers all protections given to a property actually included until the eligibility is resolved.
389 F.Supp. at 1117. The court believed, however, that the Interior Secretary’s May 8,1974, Federal Register Notice, which stated that Moanalua “may be eligible” for inclusion in the Register, was not equivalent to a determination that the Valley “i's eligible.” We cannot accept this purported distinction.
As noted above, the regulations define “eligible for inclusion” in the National Register as meaning “likely to meet the National Register Criteria.” We are absolutely unable to perceive any meaningful distinction between “may be eligible” and “is likely to meet the criteria” for inclusion in the National Register. Furthermore, in his Federal Register Notice, the Interior Secretary specifically stated that the “may be eligible” designation entitled the listed properties to protection under the relevant Executive Order and “other applicable Federal legislation.” This is the same protection that is provided under an “is eligible” determination. Finally, subsequent to the District Court’s decision in this case, the Interior Secretary has resolved any remaining doubts by publishing a new Federal Register Notice concerning Moanalua. This Notice specifically states that the Valley has been determined “to be'eligible for inclusion in the National Register.” 40 Fed. Reg. 23906-07 (1975).
The District Court also concluded, and the appellees here contend, that since the Interior Secretary specifically determined Moanalua not to be of national historic significance, the question whether the Valley [441]*441is significant in State or local history should be resolved solely by the Hawaii Historic Places Review Board. As previously noted, that Board has classified the Valley as being of only “marginal” historic significance. In our view, the District Court and the appellees have misconstrued section 4(f).
Section 4(f) applies to all properties that “the Federal, State, or local officials having jurisdiction thereof” determine to be of “national, State, or local significance.” Under the NHPA, the Interior Secretary’s “jurisdiction” to determine historic significance is not limited to properties of national importance.13 In defining the National Register, the NHPA speaks in terms of properties “significant in American history, architecture, archeology, and culture,” 16 U.S.C. § 470a(a)(l) (1970). To us, it appears beyond dispute that such significance can be found in properties that relate only to the history of a particular region, state, or locality. See 36 C.F.R. § 800.10 (1975); H.R.No.1916, 89th Cong., 2d Sess. (1966) reproduced at 1966 U.S.Code Cong. & AdmimNews, p. 3307. Since the Interior Secretary is the only official authorized to name properties to the National Register, we have no doubt that he has “jurisdiction” to determine whether properties have state or local historic significance.
Under section 4(f)’s disjunctive language, if any of the officials having jurisdiction to determine that a site has national, State, or local historic significance, so decides then section 4(f) applies. Consequently, the Interior Secretary’s determination that Moanalua is eligible for inclusion on the National Register as a site of local historic importance is not vitiated, and cannot be vitiated, by the State Review Board’s finding that the Valley has only “marginal” significance. See Named Individual Members v. Texas Highway Dept., [442]*442446 F.2d 1013, 1025-27 (5th Cir. 1971), cert. denied, 406 U,S. 933, 92 S.Ct. 1775, 32 L.Ed.2d 136 (1972) (section 4(f) applicable even though city officials had determined that city-owned parkland was of “secondary” importance to the construction of a freeway).14
In our court, the appellees have advanced three additional arguments which, if correct, might serve to validate the Transportation Secretary’s decision that section 4(f) does not apply to the Moanalua Valley. First, taking a position different from that adopted by the District Court, the appellees assert that, even though the Secretary of the Interior may have determined Moanalua to be eligible for inclusion in the National Register, that determination does not constitute a finding of Moanalua’s “historic significance” for the purposes of section 4(f). Appellees argue that section 4(f)’s application is narrowly restricted to properties that are actually included in the National Register or perhaps a similar state or local compilation of historic sites. We disagree.15 In our view, the Interior Secre[443]*443tary’s determination that Moanalua “is likely to meet” the established National Register Criteria constitutes a finding that the Valley has historic significance. A contrary conclusion would exalt form and ignore substance.
In making this argument, appellees rely on two paragraphs of a letter written by former Interior Secretary Morton concerning his determination that Moanalua is eligible for inclusion in the National Register. Secretary Morton wrote that his determination of Moanalua’s eligibility for listing in the Register did not trigger the requirements of section 2(b) of Executive Order 11593 and that the Department of Transportation remained “. . . solely responsible for determining which provisions, if any, of the . . . Department of Transportation Act . . . are applicable” to H-3.16 We do not interpret Secretary Morton’s letter as broadly as do the appellees. Section 2(b) of Executive Order 11593 establishes special requirements for the protection of historic sites that are located on lands owned by the United States. Since Moanalua is privately owned, the section, under its own terms, does not apply. Furthermore, there is no question that, as Secretary Morton stated, the Secretary of Transportation, not the Secretary of the Interior, is responsible for making the initial determination whether section 4(f) applies to a particular highway project.17 In [444]*444making that determination, however, the Transportation Secretary must ascertain whether the project will use land from a site of historic significance, as determined by the Interior Secretary, or state or local historic preservation officials. Moreover, as here, the Transportation Secretary’s decision is subject to judicial review.
Appellees next assert that the Interior Secretary’s determination that Moanalua is eligible for inclusion in the National Register is invalid because the determination was not made in accordance with the procedures set forth in 36 C.F.R. § 800.4(a)(2) (1975). In pertinent part, that regulation reads:
If [the Federal] Agency Official [responsible for a specific project] determines that a property [that will be adversely affected by the project] appears to meet the [National Register] Criteria, or if it is questionable whether the Criteria are met, the Agency Official shall request, in writing, an opinion from the Secretary of the Interior respecting the property’s eligibility for inclusion in the National Register. The Secretary of the Interior’s opinion . . . shall be conclusive for the purposes of these procedures.
Appellees contend that, since the Secretary of Transportation, who was the agency official responsible for H-3, did not request the Interior Secretary to determine whether Moanalua was eligible for inclusion in the National Register, the Interior Secretary had no authority to make such a determination.
Initially, we note that in making this argument appellees expose their own hands, some of which are not wholly clean. The regulation expressly and unambiguously provides that “if it is questionable” whether a property meets the National Register Criteria, the responsible agency official shall request the Interior Secretary’s opinion. It is manifest that throughout 1974 it was at least “questionable” whether Moanalua was eligible for the National Register. The Valley had been nominated for the Register as early as March, 1973, and in 1974, the Valley was the subject of studies by the Advisory Council and the State’s historic review board. On May 8,1974, the Interior Secretary published an official notice that the Valley “may be eligible” for the National Register. The Transportation Secretary here seeks to avoid the effects of his own, wholly inexcusable, noncompliance with the regulation.
Furthermore, we find nothing in NHPA or the implementing regulations that would preclude the Interior Secretary from determining, on his own initiative, whether a property is eligible for inclusion in the National Register. Such could prove to be one of his most important and enduring contributions. The procedures set forth in 36 C.F.R. § 800.4 (1975) apply only to the special situation wherein a property not previously evaluated in the light of the National Register Criteria, is in imminent danger of alteration or destruction because of an on-going or proposed Federal project. Here, before the Interior Secretary acted, Moanalua had been nominated for inclusion in the Register by the Moanalua Gardens Foundation and had been studied by the Secretary’s Advisory Board on National Parks, Historic Sites, Buildings, and Monuments. We believe that the Interior Secretary’s determination was well within his power under the Congressional authorization conferred by the NHPA.
Finally, appellees have suggested that the Transportation Secretary’s review and approval of the Environmental Impact Statement (EIS) pertaining to H-3, which includes some material concerning Moanalua’s historic significance, as well as discussions of several alternatives to H-3’s pro[445]*445posed route through the Moanalua Valley,18 constitutes compliance with section 4(f). Section 4(f) does not require the Transportation Secretary to set forth specific findings and reasons for approving a project that will use land from parks or historic sites.19 Citizens to Preserve Overton Park, Inc. v. Volpe, 401 U.S. 402, 417-19, 91 S.Ct. 814, 824, 28 L.Ed.2d 136, 154 (1971). Nevertheless, a court reviewing the Secretary’s 4(f) decision must satisfy itself that the Secretary evaluated the highway project with the mandates of section 4(f) clearly in mind. Id. at 416,91 S.Ct. at 823,28 L.Ed.2d at 154. On the administrative record, the Secretary’s consistent position was not that he had complied with section 4(f) but that the statute was altogether inapplicable. In the light of that consistently recorded position, it is not possible, with factual accuracy, to conclude that the Secretary evaluated H-3 with the explicit directives of 4(f) firmly in mind. Furthermore, we note that the EIS provides no evidence that the Secretary complied with section 4(f). While the document does contain some discussion of the advantages and disadvantages of several alternatives to H-3, as the roadway is now planned, the analyses do not attempt to demonstrate, or purport to establish, that each of the alternatives is not “feasible or prudent,” as those terms are defined within the context of section 4(f). Id. at 411-13, 91 S.Ct. at 821, 36 L.Ed.2d at 150.
We conclude that the Secretary of the Interior has determined Moanalua to be eligible for inclusion in the National Register of Historic Places and that this determination entitles the Valley to the protections Congress has established for historic sites in section 4(f). We further conclude that the Secretary of Transportation did not comply with the requirements of section 4(f) before he approved Federal funding for H-3.
IV. Other Issues
Appellants contend that the Secretary also failed to comply with section 4(f) with respect to Pohaku ka Luahine, which, as we have heretofore noted, is included in the National Register. Because the petroglyph rock has once been moved and now rests a short distance from its original location, the District Court concluded that the rock, and its present surroundings, do not constitute an “historic site” for the purposes of section 4(f). 389 F.Supp. at 1116.
After careful consideration, we cannot escape the conclusion that Pohaku ka Luahine, and its immediate environs, qualify for protection under section 4(f). It is clear that the rock was originally located in the Valley, and it is inseparably linked to historic events that there occurred long since. Consequently, so long as the rock remains in the Valley, even though it may stand a few feet from its original location, we believe that it forms the basis for an historic site. Further, we believe that H-3, which will pass near the rock, will “use” land from that historic site. See Brooks v. Volpe, 460 F.2d 1193, 1194 (9th Cir. 1972) (a proposed highway that would encircle a public campground would “use” that campground).
In the particular circumstances of this case, however, Pohaku ka Luahine’s fate, like its historic significance, is linked to that of the Moanalua Valley. If the Secretary validly determines that there is no “feasible and prudent” alternative to the alleged desecration of the Valley, there will be no such alternative to the use of the petroglyph rock. Consequently, if the Secretary makes [446]*446such a determination, the 4(f) inquiry with respect to the rock must be whether there has been “all possible planning to minimize harm.”
Appellants have presented three other issues to us. They contend that the EIS for H-3 and the 4(f) statement pertaining to the Pali Golf Course are inadequate and that the H-3 project is not grounded in a continuing comprehensive State and local transportation planning process, as is required by 23 U.S.C. § 134(a) (1970). Because of our decision as to Moanalua Valley and Pohaku ka Luahine, we believe that we should not consider these issues at this time. It is altogether possible that future developments will moot these issues. In the event that the Secretary does conclude that there is no “feasible and prudent” alternative to the routing of a multi-lane highway through Moanalua, the District Court will reconsider that conclusion and these other issues in the light of all information that will then be available.
The District Court’s Order dissolving the injunctions against construction of H-3 is reversed. On remand, the District Court will enjoin construction of the highway until such time that the Secretary can demonstrate his full compliance with section 4(f) as the statute applies to Moanalua Valley and Pohaku ka Luahine and has made a determination in harmony with the statutory requirements.
REVERSED AND REMANDED.
