counted. These ranged from 3 inches to 16 inches in diameter, and
sections over 3 feet long were exposed. Each beryl is surrounded by a
layer of oligoclase feldspar one-half inch to 3 inches thick, the beryl
crystals are variously colored pale bluish green and yellowish green,
and light and dark golden yellow. Most of them we opaque, but some
contain translucent portions. Many crystals have been broken, either in
mining or by collectors looking for gem material, and hundreds of
fragments of beryl are scattered over the dump. No transparent gem
beryl was observed, but the impression gained by a study of the deposit
was that gem beryl might be found by further excavation.
