Those posted coordinates look like a mistake but they're not. They are a confluence.
A confluence is a location were latitude and longitude integer degrees intersect. No matter where you are in the world you are within 49 miles of a confluence and one just happens to be in Three Falls Woods! There are people who visit confluences and log them online, just as we do geocaches. Below is a link to the relevant website with more information.
The Degree Confluence Project
The cache is not at the posted coordinates. You must project a waypoint from those, so many zeroes, a distance of 1375.4 feet at a bearing of 242.657 degrees.
Obviously, you don't have to visit the confluence but please let me know if you do. Parking coords provided. Enjoy the hike!
