Green beryl crystal
Another green beryl crystal
An opaque, green beryl crystal from the Whippet #8 mine which is high up the mountain (approximately 7000 ft elevation) near our camp. The main minerals from this mine were petalite, tapiolite, ghanite, beryl, feldspar and spessartine garnet.
Another opaque, green beryl crystal. We also found some blue beryl crystals of the same quality as this one.


Tapiolite
Cows and mine dump
Tapiolite crystals, which have been damaged, within matrix. Tapiolite is a black, metallic, tetragonal mineral with a (Fe,Mn)(Ta,Nb)2O6 composition.
Starting the trip back to Denver, I passed these cows with one of the dumps in the background.
