Iron Mountain is one of the many hills in the Housatonic River Valley (this one situated east of the river above the village of Kent). Here there is grey-to-pink gneiss along with black mica (biotite).


The area was used for agriculture. 

The area was reforested following this agricultural use.

Iron Mountain is named for one of the iron mines of the area. 

mid- to late-1800s  --  the charcoal industry cleared nearly all the drier forest.

Remnants of charcoal pits are still visible

This is a 1.5 mile long walk over the summit of Ore Hill. The path goes through an old apple orchard and across a charcoal pit. The trail heads generally southwest and then begins a counter circular walk around the summit of Ore Hill, and then back to the entrance.

From the north of the parking area the trail leads west downhill, then turns south to an abandoned orchard. The trail exits through a stone wall, turns west (right) and meets the loop-trail junction.
