Wreckage of Time: The Fish Creek Badlands

Date: 
Saturday, March 7, 2015 - 9:00am to 5:00pm

Instructor: Paul Remeika
$70 / $60 for ABF members

Join our resident expert Paul Remeika on a geologic visit into the stony depths of Split Mountain Gorge to see the initial rock record of sedimentation within the Salton Basin. Here, an immense cavalcade of rocks chronicle the Miocene Epoch, when enormous forces of moving water conveyed material from an evolving upland source onto a low basement surface, making for beautifully-preserved aprons of debris freighted with boulders. Add a few landslide deposits, cap it off with some of the best marine deposit outcrops from the Gulf of California, and introduce the Colorado River delta to the area, and what we have here is outstanding in-your-face geology. We will follow Fish Creek Wash on a fantastic journey up-section through a host of sedimentary layers representing different depositional environments to Sandstone Canyon. Several short excursions will introduce participants to the complex history of the badlands highlighted with outstanding shellfish deposits from the northern Gulf of California, petrified (silicified) woods that once occupied the river delta and their significance, and rare footprint impressions from an extinct vertebrate fauna we have no solid body fossil record of.
