When the CCC (Civilian Conservation Corps) back in the 1930s built the trails and lodge in the state park, they discovered rocks and Indian tools on the cliff. They rearranged rocks to create a wall which they figured was the configuration of the orignal "fort" wall.
Fort Wall?
What was the use of the area? No one knows for sure. One of the two most widely mentioned theories for the site's settlement was that the "fort" was that it really was a fort used as a defensive establishment. Given the nature of the bluff looking over the valley and that the only access point would be through the top of the bluff, a stone wall along that access definitely would provide an excellent defensive position. The other leading theory was that settlers used the space as a large pen, with the wall being used to confine gathered animals. However, no direct evidence supports fully either of these two theories.
After looking at the fort, we walked along the bluff edge. Yes, the trail literally came to the edge of the cliff and we caught a good view of the valley and of the steep dropoff to the base of the bluff.
Viewing the Bluff
If it were wet, the trail along the cliff side I wouldn't suggest taking. But since it was dry, it was nice to get a real view of the terrain. After winding along the edge, we took one more look of the stone wall and headed back down.
The trail is relatively short, but for its size, it does offer an interesting slice of the past and scenic views. I'm definitely curious how the valley looks in summer from the trail along the bluff edge. It's definitely worth hiking.
