Personally, as a native of Southwestern Pennsylvania, it confounds me that the beautiful Laurel Highlands are not absolutely smothered with bouldering junkies. Admittedly, I haven't visited many true destination sized areas in my travels, but I have traveled extensively throughout the Laurel Highlands and am continually amazed by the amount of rock that I still find. I have spent so much time exploring and climbing at new areas that I haven't visited a single documented area more than 6 times in 3 years of climbing. As a local,I understand the relative solitude of the area can be a bit of a problem,but then again, climbers have never been known as a group to avoid solitude. All in all, this post is a plea, not for my sake, but for anyone who reads it. Don't just look at the page on mountainproject then write it off. Go there and pick a few plums for yourself. Below is a series of coordinates for areas that have solid potential and very little development and documentation. Besides all being on public lands, they are all within about half an hour of each other and within an hour and a half drive from Pittsburgh.
If you go to any of these places, have fun, respect the land, and enjoy the scenery!
