The Rune Stones is a small, stand-alone boulder field offering some free standing Antietam Quartzite boulders to climb on. The overhanging faces tend to have positive holds and therefore offers some fun dynamic climbing that is at most moderate difficulty. The stone is mostly super solid and sometimes just pure white quartzite!
Not a super high quality or major spot by any stretch, but if you're wanting to boulder some, avoid crowds and you're already in the area, then this spot will meet your wants/needs!
