Pine Swamp Mine | Harriman State Park | NY
By far my favorite part of Harriman that I’ve explored thus far. The adit of this mine must have been at least 60-70 feet tall and 20 feet wide. After an hour or so exploring in and around the adit, I tried to make my way up to the openings at the back of the mine, only to find fallen trees and brush completely blocking the way.
