I think you have the term mixed up. Easements are public rights of way through private property, not the other way around. The highpoint of Monument Peak is on private property, not public. There is a trail that crosses near the summit on a public easement (at the generosity of the landowner), but the side road leading to the summit knoll is clearly marked Private. That said, I've wandered up there several times and there is little chance that anyone will care since there are no installations at the highpoint.
