Yukon Phosphates, Gormanite

The Phosphate occurrence area in the Yukon is the type locality for Gormanite. The beautiful greenish sprays of crystals are very attractive, especially for a rare mineral! They are actually gormanite-souzalite since both minerals are often present on a specimen, in the same CRYSTAL but indistinguishable. They are a solid solution but I'll refer to these as gormanite. No new specimens have been collected for years at this remote site. Here are some nice examples from an old cache.
