Yuha Basin Oyster Beds, April 3, 2012

      Unfortunately, we had to cancel the trip which was scheduled for March 20, due to a lack of 4wd vehicles.  We managed to get enough vehicles together to haul 10 of us on April 3.


      The weather cooperated perfectly for us!  Our BLM map was a little help, but it shows the Oyster Beds in the wrong area. The map managed to direct us to the BLM camping area, and then Kenny Irwin’s 6th sense, or internal GPS, led us to the right location! We literally hit the jackpot!! 

 

      Fred Kalmar located one hill that is totally crusted with layers of oyster shells. These shells are the remains of the Miocene time period of about 6 million years ago at which time the oceans in the Imperial Geologic Formation covered most of Imperial and central Riverside Counties.


      Once we found this location, we did not explore for sandstone concretions or petrified wood.  We did find some calcite rhombs and some sheets of gypsum. 


      With full buckets and satchels we headed for the Travertine Grill in Salton City for some cooling refreshments.
