Corundum var. Ruby
near Upland, Cascade Canyon, California
Twice a month our Gallery sponsors a free, guided monthly, public mineral collecting trip. This Sunday we went ruby collecting in Cascade Canyon, California. We had a wonderful turn out, over 20 people! The weather was warm and sunny, and everyone found plenty of specimens to take home. This is one of our most popular mineral collecting trip locations. Below is a map to the location.
