Gem-o-rama


Bruin Geological Survey will be going on its first trip of the year next weekend (10/14-10/15) to Searles Lake in Trona, CA for the 76th annual Gem-o-Rama mineral hunting extravaganza. Once a year, the Searles Valley Minerals mining company opens up its grounds to the public to collect minerals such as hanksite, sulfohalite, borax, and pink halite from under a briney crust. Hanksite is a rare mineral only found in two places in the world, Trona, CA and Lake Katwe in Uganda, Africa. 

We will be leaving Friday evening to avoid traffic and returning on Sunday afternoon. We plan to camp about 15 minutes away from Trona.

Minerals to be found: cluster and barrel hanksite, trona, borax

 

Saturday at 2:30pm Blow Hole Field Trip
