Mountain rocks fascinate us. Most of the time in the Alleghenies, the large boulders sitting on the landscape are evidence of crumbling mountains. Sometimes they are evidence of seams of rock that were harder than what was around them, which has since eroded away. Other times the rocks are "erratics," dropped by a receding glacier when the load became too heavy.
Fortunately for us, the folks that design, mark and maintain trails appear to be fascinated by big rocks, too. We have chosen many hikes over the years because the routes took us to, over and around iconic rocks and rock "fortress" formations.
