I took a quick walk through a few exhibits at the Tucson Gem, Mineral, and Fossil Showcase that got underway officially today (wheeling and dealing has been going on all week as vendors unloaded their trucks and set up displays).
Here are a few Arizona specimens that caught my attention.
Top right- chrysocalla from the Ray Mine covered by hundreds of tiny clear quartz crystals.
Top left - 3200 lb section of petrified wood, described as Douglas fir from near Petrified Forest National Park. "The tree was nearly 5 feet across and probably centuries old when it fell."
Bottom - Wild West Rocks from Show Low, AZ with a garden of petrified logs.
