Only part of it is in the state-owned Forest Preserve; the summit and the most common access route are owned by descendants of railroad magnate Jay Gould, a native of the region, who closed the peak to the public indefinitely in January 2021.

[4] Graham is near the eastern end of the range beginning at Barkaboom Mountain in Delaware County in the west and centered around the lengthy Mill Brook Ridge.

[6] Since Dry Brook drains into the East Branch above Pepacton Reservoir, this puts the north slope of the mountain within New York City's water supply system.

The United States Geological Survey benchmark indicating the mountain's 3,868-foot (1,179 m) height of land is at the northwest end, near the ruins of the relay station.

[7] The south slopes, up to almost 3,500 feet (1,100 m) on the summit ridge's southwest spur, are publicly owned Forest Preserve in the Big Indian-Beaverkill Range Wilderness Area.

The summit itself is covered with a pygmy forest, unique in the Catskills, with its black cherry and mountain ashes barely taller than average human height.

He has concluded that all peaks represent different stages of forest evolution, in which the stunted and twisted ridge hardwoods gradually have replaced balsam fir over the last 8,500 years.

[11] The Catskills were formed 250-350 million years ago, during the Devonian and Silurian periods, when the sands and silt that had eroded from the Acadian Mountains to the northeast collected in a river delta at the mouth of the shallow inland sea that is now the Allegheny Plateau.

The road ahead continues the gentle ascent until 3,400 feet (1,000 m), where it climbs more sharply up a series of switchbacks, passing some of the balsam firs on the slope at higher elevations.

The old relay station, a one-story cinderblock structure with no remaining roof and the three steel supports that can be seen from various viewpoints in the area near the mountain, is at the center of a large clearing.

An informal poll of 3500 Club members has found Graham ranks with nearby Eagle as their least favorite summit among the Catskill High Peaks.

Rough use paths lead along the ridge through the pygmy forest to views over the Dry Brook valley and Big Indian, Eagle and Fir mountains to the northwest, and Doubletop and the Beaver Kill's headlands to the southeast.
