I've heard that PA is rocky but nothing prepared me for the boulders that are the path on this state. The combination of rocks, rain, humidity and dry or scarce water make this state so challenging. I have 30 more miles until I reach the NJ border. One more challenge - snakes. I haven't seen any rattle snakes but other hikers have - among the rocks.  Today I climbed a rocky, steep trail from Lehigh Gap. I think it was the most challenging area so far on my hike. 

I could look down over the Gap and view the superfund site in Palmerton.  The redeeming feature was loads of blackberries at the top.
