The cache is not at the above coordinates!
You must find the Clarks Pond Depot Trail cache (GC15AA3) to get the coordinates for this one. (Recently archived...so here you go: N 43° 37.932 W 070° 19.059) These caches are located along a different part of the trail than the other three. Most of the trail is paved until the very last part. Be careful near the cache location. Might be slippery, so watch your kids here. (Otherwise, the terrain is a 1.5) You are looking for a small locknlock with logbook and a few small items to trade. For a longer hike, you can walk to the other caches as well. Have fun and Happy Cachin'!
