the park. Macfarlane (1819–1885) was a noted attorney, coal geologist, geological guidebook writer, and enthusiast of the area near what was then called Green Lake (later renamed Glacier Lake to avoid confusion with the nearby Green Lake in Fayetteville, NY). The resort's offerings included picnicking, boating, fishing, croquet and archery, but it closed after a few years. The central part of the current park, amounting to and including Glacier Lake and the fossil waterfall, was bought by Mary Clark Thompson in 1915. Thompson had learned that the fossil waterfall was being considered for a limestone quarry; just to the east were the enormous limestone quarries of the Solvay Process Company. Thompson gave this tract to the New York State Museum, with the stipulation that the land be preserved as a memorial to her father Myron H. Clark, who had been governor of New York State from 1855-56. Clark Reservation became a state park in 1926. The New York State executive budget plan for 2010-2011 called for Clark Reservation State Park to be closed as a budget-cutting measure. The park closings were reversed for the 2010 season by legislation passed on May 28, 2010. Ferns Clark Reservation is known for the diversity of fern species which grow there; in a 1994 survey, 26 fern species were identified. The park is presently the principal site in the United States preserving American hart's tongue fern. This fern is quite rare in North America; its presence on the continent was first discovered in 1807 by botanist Frederick Pursh at nearby Split Rock in Onondaga County. The second half of the 19th Century was a period of popular enthusiasm for ferns that has been called "pteridomania". Discovery of additional "stations" for hart's tongue, and indeed rediscovery of the original Split Rock station, were subjects of considerable interest in the 19th century. The station near Glacier Lake was first reported in 1866 by J. A. Paine, and several stations are now known within Clark Reservation. Because of its rarity, censuses of the fern in this region of New York have been reported periodically since 1916. In 1989, this species was declared as endangered in the United States. The most thriving site for hart's tongue through about 1925 was not Glacier Lake, but a second similar lake about due east. As with Glacier Lake, this lake was known by several names, including Green Pond, Green Lake, East
