As a child, I was always fascinated by and on the hunt for "pretty rocks". Granted, 10-year old me may not have had the best eye for what constituted a "pretty" rock, but I always enjoyed the hunt. '

Apparently some things you never outgrow! Black Rock Spring in Utah's West Desert is home to a large deposit of Obsidian. Born from the volcanic activity in the area millennia ago, Obsidian is a smooth volcanic glass. It was prized over the centuries by people for making arrow heads and other sharp tools, as it can be shaped relatively easy by chipping.

Today, Black Rock Spring makes a great family friendly roadside attraction to spend some time hunting for pretty rocks. Obsidian is generally black, but with a bit of hunting around, Black Rock Spring also contains snowflake obsidian that contains small white specs resembling snowflakes, as well as other red speckled obsidian. The area around the spring is a bit picked over, but wandering away from the spring will yield plenty of interesting rocks. A sunny day is recommended, as the obsidian glints brightly in the sun and is easiest to spot on sunny days.
