There are several stories on how Hell's Hollow received it's name. Here is one I found:
"Hell's Hollow" was named by the early settlers, and is an extremely suggestive appellation, for a gloomier place can hardly be found. It is related that the origin of the name comes from the fact that a traveler in an early day became benighted and passed the night in the hollow. When asked the next day where he had slept, answered that he "didn't know, unless it was in hell!" http://www.usgwarchives.org/pa/lawrence/1877/sliprock.htm, History of Lawrence County Pennsylvania, 1770 - 1877, by S.W. and P.A. Durant.In another version, the blazing iron and lime furnaces at the time convinced the lost traveler that he had wondered into Hell itself.
Contrary to its name, Hell's Hollow is quite beautiful. It is well know for its wild flowers which eventually I will have photos of. The trail winds along Hell's Run and end at a spectacular waterfall near an old lime kiln.
I will be posting more photos and info later. If anyone has their own stories, please feel free to post in the comments.
