Location: Approximately 4 Conestoga Boulevard across the street from Conestoga River Park on Lancaster Conservancy property. 39°56’25.7″N 76°23’09.7″W.
History Brief: Hidden in the forest near the Conestoga River lies a huge rock outcropping covered with mysterious carvings. Local historian Earl Rebman first identified the boulder 50 years ago in his Conestoga River Watershed book. Rebman wondered what the hand pointed to, suggesting possibly buried treasure or a hidden mine.
Clue: Locate the mystery stone and identify the symbol hidden beneath my thumb in the image below? (five-letter word)

Rest of the Story: A few years ago, while reading Earl Rebman’s book, Conestoga River Watershed, I came across the most curious passage and photo.
The caption from this 50-year-old book read:
Mysterious carvings buried deep in the woods on a huge rock outcropping near the Boulevard. What does the hand point to—buried treasure or a hidden mine—could pirates have possibly traveled this far upstream to bury their loot—who will be the one to discover the answer?
I instantly decided I would be the one to discover the answer. The first challenge was figuring out where the mysterious stone was hiding. It took over a year of looking, but I finally found the rock. That’s where your search continues.
As for what it means, I’m curious if it points to the hidden location of the legendary cache of gold guarded by a seven-foot-tall Native American ghost (square 9)!
Additional Location Details
From Safe Harbor Dam, head north on River Road to Conestoga Boulevard.
Once on-site, look for the 35 mph speed limit sign. From that location, carefully cross the road. Here are the GPS coordinates. (39.940461, -76.386017)



Less than 20 feet off the road and perpendicular to it is the rock in question. Several strange inscriptions can be found carved into the surface. The most prominent is a large F. S.18.79. The answer lies below it, where my thumb is.
