Field Trip To A Vertebrate Fossil Locality In The Coso Range

Post by Inyo » Sat Apr 22, 2017 7:44 pm

This subject doesn't strictly pertain to Death Valley, of course--but, it's pretty close, anyhow.

It concerns a field trip to the Coso Mountains, not too far west of Death Valley, proper--in the vicinity of Olancha.

Just recently, over at http://inyo.coffeecup.com/site/coso/cosofieldtrip.html , I uploaded a page called "Field Trip To A Vertebrate Fossil Locality In The Coso Range, California." It's a cyber-visit to the upper Miocene to upper Pliocene Coso Formation in the Coso Mountains--a roughly six to three million year-old geologic rock deposit that yields quite a number of mineralized mammalian remains, including a vole, rabbits, meadow mice, a hyaenoid dog, mastodon, camelids, horses (including the famous Hagerman Horse--named for its spectacular occurrences at Hagerman Fossil Beds National Monument, Idaho--one of the earliest examples of the genus Equus, which of course includes all modern horses and equids), a large-headed llama, and a bear.

The Coso Mountains fossil localities presently lie within the Coso Wildnerness--so quite obviously you can no longer drive into the Coso Formation badlands--and you can't keep what you find there without a special BLM permit.

But you can still hike through the geological/paleontological wonderland and take all the photographs you want.

Thanks for the writeup and pictures! For hiking out there should we plan to be out all day? I realize a certain amount of skill and probably luck is needed to locate fossils.

I also saw that you had a lot of other interesting things to read. It will take a while to absorb those.

best regards,
