Treman State Park''' is a {{convert|1110|acre|km2|adj=on}} state park located in Tompkins County,<ref name=RIoG_PS/> in the Finger Lakes region of New York in the United States. The park is situated in the towns of Ithaca, Enfield and Newfield.
==History== Robert H. Treman first purchased land surrounding Enfield Falls in 1915, and worked to improve the property by planting over 1,000 trees. He and his wife, Laura Treman (Hosie), donated the land to New York State in 1920 for the establishment of '''Enfield Glen State Park'''.<ref name=50years>{{cite book |title=Fifty Years: New York State Parks, 1924-1974 |url=http://nysl.cloudapp.net/awweb/guest.jsp?smd=1&cl=all_lib&lb_document_id=104152 |page=10 |publisher=Natural Heritage Trust |date=1975 |author1=Natural Heritage Trust |author2=New York State Office of Parks, Recreation and Historic Preservation |author3=New York State Council of Parks & Recreation |archive-date=March 29, 2019 |access-date=October 8, 2016 |archive-url=https://web.archive.org/web/20190329225528/http://nysl.cloudapp.net/awweb/login.jsp?bp=3 |url-status=dead }}</ref><ref name=Kammen2004>{{cite book |last1=Thompson |first1=Susan |editor1-last=Kammen |editor1-first=Carol |title=Place Names of Tompkins County |date=2004 |publisher=Office of the Tompkins County Historian |location=Ithaca, New York |page=49 |url=http://www.tompkinscountyny.gov/files/historian/placenames/PlaceNamesofTC.pdf |access-date=July 7, 2015 |chapter=Town of Enfield |archive-date=December 27, 2016 |archive-url=https://web.archive.org/web/20161227094606/http://www.tompkinscountyny.gov/files/historian/placenames/PlaceNamesofTC.pdf |url-status=dead }}</ref> The park was renamed in Robert H.

The Enfield Falls Mill and Miller's House was listed on the National Register of Historic Places in 1979.<ref name="nris">{{NRISref|2009a}}</ref>
==Geology== The rock formations within the park are primarily made of Devonian shale and sandstone.<ref name=Cayuga_Geology_Cornell>{{cite conference |author=Department of Geology, Cornell University |title=Geology of the Cayuga Lake Basin |conference=31st Annual Field Meeting of the New York State Geological Association |pages=1–6 |date=May 1959 |location=Ithaca, NY |edition=2 |url=https://ottohmuller.com/nysga2ge/Files/1959/NYSGA%201959%20Cornell%20Bookmarked.pdf |access-date=3 November 2021}}</ref> These rocks formed in horizontal layers, creating flat slabs and angular edges as they erode and fracture.
The valley and waterfalls formed since the last ice age — within the last twenty or thirty thousands years — roughly in-line with previous streambeds. However, around Lucifer Falls, the current streambed completely deviates from its now drift-filled interglacial streambed (where the creek flowed in-between periods of glaciation).<ref name=Cayuga_Geology_Cornell /> This path of new erosion is distinguished by its steep cliffs and narrow gorge.
Additional rock formations near Lucifer Falls include current ripple marks,<ref name=Cayuga_Geology_Cornell /> indicating the direction the creek used to flow.

==Park description== Robert H. Treman State Park is located along State Route 327, just west of state routes 13, 34, and 96. The park offers an outdoor swimming area at the base of a waterfall, picnic tables, playing fields, hiking and camping.
The park has numerous waterfalls along a {{convert|4.5|mi|km|adj=on}} round-trip hike. The hiking trails follow Enfield Creek, giving many views of the rock formations in the deep, narrow gorge known as Enfield Glen. A natural swimming pool is located at the easternmost waterfall, known as Lower Falls. Lucifer Falls, a {{convert|115|ft|m|adj=mid|-tall}}, multi-tiered cascading waterfall, is a short hike from the western portion of the park. Views of Lucifer Falls can be found along the gorge trail, in addition to overlooks along the rim trail. The Finger Lakes Trail skirts the southern edge of the park.
Because of dangerous conditions created by snow and ice, most of the park's trails are inaccessible in the winter. Visitors can view Lower Falls year-round.
