Long Mountain was a good hike.  Nick, Justin, Tim M., and Jay went up to Long Mtn.  Jay left and Vinny joined us for a revisit to Bare Mtn. later in the afternoon.  Looking at this picture I'm pretty sure the "horse caves" are close to the top of Mt. Norwottuck and down a little to the SE (left).  What is the other feature?  It's more to the direct east, farther from the summit, and quite a bit larger.  Next time we are in that area I think we need to go explore it - Stay tuned!

UPDATE:  We did go back, and made it to those cliffs.  Cuddeback Trail ends there, so I have been calling it "Cuddeback Cliff".  It's a nice view of Long Mountain from there.
