11. Id., at 188. The 1910 Act is the Act of June 25, 1910, ch. 421,36 Stat. 847, the "Pickett Act," which is one of the statutes whose authority the President
expanded with the acquiescence of Congress, and the Act of June 4, 1897, ch. 2, 30 Stat. II, 36, which expressly authorized the revocation or vacating of
executive orders or proclamations creating forest reserves under the Act of March 3, 1891, ch. 561,26 Stat. 1103 (codified at 16 U.S.C. § 471 until its repeal
by FLPMA in 1976). In the National Forest Management Act (Pub. L. 94-588, 90 Stat. 2949, 2957), Congress provided that forest reserves could only be
returned to the public domain by an act of Congress. 16 U.S.C. 1609(a).
12. This is especially true with respect to authorities which Presidents applied expansively in a pattern of actions to which Congress acquiesced. United States
v. Midwest Oil Co., 236 U.S. 459 (1915). However, there has been no pattern or even an instance of Presidential revocation of monument designations. In
addition, arguably the era of expansive Presidential powers was reversed by FLPMA.
13. H.R. Rep. 94-1163 at 9 (1976).
14. TVA v. Hill, 437 U.S. 153, 189 (1977), quoting Morton v. Mancari, 417 U.S. 535, 549 (1974).
