The Cliffhanger pocket was discovered by Carl Auclair in a very steep area of cliffs between the K.D. pocket and the Ohio mine in the Amphitheater east of Ouray, Colorado, in 2004. The name comes from the fact that Carl had to use climbing harness to collect much of the pocket area. There were two main pockets, a lower, smaller pocket, and a larger upper pocket. The upper produced the largest singles and groups to come out of the Cliffhanger pocket. The quartz crystals from here are milky, and with small single milky quartz crystals growing perpendicularly from the prism faces. The pyramid faces are well developed and glassy. Quite a few quartz epimorphs after calcite were found in both pockets, and were well formed and up to 30mm in length. Carl pretty much cleaned out the pocket in 2005.
