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.[5][6] The park was renamed in Robert H. Treman's honor following his death in 1937.[5]
The rock formations within the park are primarily made of Devonianshale and sandstone.[8] 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).[8] This path of new erosion is distinguished by its steep cliffs and narrow gorge.
Additional rock formations near Lucifer Falls include current ripple marks,[8] indicating the direction the creek used to flow.
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 4.5-mile (7.2 km) 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 115-foot-tall (35 m), 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.
