Like the other preserves of the Indian Brook Assemblage (Mildred E. Grierson Sanctuary and Marian Yarrow Preserve), Mount Holly is composed largely of upland mixed hardwood forest. In the several acres of meadows at the preserve look for wildflowers or look up into the sky for a glimpse of a red-tailed hawk searching for prey. There is also a large outcrop of cliffs made of 6 million year-old Fordham gneiss. Indian Brook, bordered by a swamp, runs south along the eastern boundary and eventually into the Cross River Reservoir.
