Charlie Dog Claim



I have a claim on a pegmatite in the southeastern portion of San Diego County.  The dikes outcrop on the top of a small hill that overlooks the Carrizo Gorge, site of the "Impossible Railroad."  The dikes dip very gently to the west and range in thickness from a few inches to a couple of yards.  The main minerals of the dike are microcline, albite, quartz, muscovite, and schorl; with minor amounts of spessartine, lithian muscovite, and beryl.

I have found numerous small vugs but only one decent pocket.  That pocket produced several large smoky quartz crystals (about 6" x 4"), one pale blue-green aquamarine that grew against the side of one of the large smokies (the aqua was about 1.5" x 0.75"), several smaller non-smoky quartz crystals and a few smoky quartz crystals with included spessartines.  They are probably the most interesting specimens.  A couple of them were doubly-terminated and included dozens of 1-2 mm spessartines.  These quartz crystals range from 1 to 4 inches long.  My favorite specimen consists of two smoky quartz crystals about 2 inches long, welded together by a schorl that is inclined about 30 degrees to their long axis.  These quartz crystals also have many included spessartines, including some that breach the surface.
