Ragged Ass Jack Mountain Locality (Ragged Jack Mountain Locality), Hartford, Oxford Co., Maine, USA
Granite pegmatite. Oxford Pegmatite Field. The original and local name for this small mountain is Ragged Ass Jack. The name was not put on the USGS topographic maps as there was then an effort thinking the name should be changed. The locality name continues to be used with its full length in the region, but there are some collectors who shorten the name from reasons of modesty. For many years, the locality was "secret" and collectors said that the wonderful chrysoberyl crystals from the place were really from Black Mountain in the nearby town of Peru. There has been additional confusion over labeling the locality as Ragged-Ass Jack Mountain is near the intersection of three towns: Hartford, Peru, and Sumner.
The locality itself is exposed on a southwestward facing cliff and a granite pegmatite dike varying from 2 to 5 meters thick is exposed on the cliff. Much of the specimen collecting was done on the talus below the cliff, but many of the boulders remaining are 3-6 meters in diameter and the poison ivy plants that grow lushly there have discouraged even eager collectors.
