Try and get out to the Yuha Basin once a year. The previous summer thunderstorms will sometimes expose cool stuff. A few years ago I found a line of vertebrae, the largest chunk was about 6 inch in diameter, I snagged a 2 inch piece perhaps a trail. Those have fallen off the wash face and disappeared most likely crushed by wheelers. Heres some pics of petrified wood that's there.
I'm guessing the trees were about 3 or 4 feet in diameter.

Heres a bone attached to a rock.
Same area as the vertebrae and petrified wood.

Well, there used to be 2 large logs with fences around them, about 5 years ago they were taken. The all-terrain vehicle damage is really bad this year. There was/is a lady at the BLM in El Centro that had a lot to do with the Yuha. I may file a complaint. Doubt they will do anything though.

FYI I did stop by the BLM and talked to Carrie. They just did some recent restore to the area around the shell bed. She wasnt happy hearing about the all-terrain vehicle damage. She would notify their law enforcement side. Apparent there may be some research digs in the near future in the area.

Not a geologist but what I'm seeing looks more like concretions. They're quite common all through ABDSP and surrounding areas and at times can sure look like petrified wood or bone. Yuha has pretty much been devastated by off roaders over the decades including the Yuha geoglyphs, trashed by some dirt bikers in the mid '70s. Jay von Werlhof tried to piece them back together but they're nothing like the old aerial photos. There's still a couple nice ones out there semi protected by their fencing and findable on GE.

Its a tree. You need to see it. One year many small animals were exposed in the face of the wash. There was a forest of some type here. Theres bigger chunks that were fenced off but were stolen.

Most of the forest runs on the south side of the shell beds in a east west direction for miles. The picture above used to be a log that was about 4 feet long 3 feet in diameter. The bone picture could be a concretion.

I firmly believe early man passed thru California much much earlier than accepted consensus. The difficulty is that 99.9% of the evidence is either buried on shore or buried off shore when sea levels were much lower. Go to Google Earth and look at the continental shelf. Way out there. That's were the earliest man evidence is. They followed the coast down 100,000's years ago and went up almost every fresh water creek or river. Unless exposed by erosion or excavated the facts are out there. Divers are always finding metates ginding stones off shore of ancestral creeks. Also back then ABSP area was much wetter and greener.

A reminder of a time 2-4 million years ago that area was covered with rivers, streams, forests and big game. Walnut, Ash, Laurel, palm, avocado, mandrone covered the area. Before that an inland ocean.

In the 60's the BLM categorized items in the YUHA. Some of the items they fenced of to prevent off-roaders from destroying. Smaller items were stolen. This forest runs south of the shell beds for miles. Something flooded this area over night so to speak and buried eveything. In the washed trees and bones are being exposed. The Yuha man which was found now is estimated to be around 5K years old. Originally they had 20K years. Some cool stuff in the Yuha. Red canyon which is north east of the Carrizo creek stage station about 5 miles has more logs, big ones. They will be more protected because of the bombing area restrictions and isolation. Theres a lot of fossils also. Looks like some hikers uncovered some old fossils in the slots a bit west Coyotes. I just love hiking the desert here. So much to see and learn.

Thanks for the Yuha Man link. Interesting story. The bones disappeared and have never been found. However, a few tiny fragments were recovered and dated to a later time. A hearth dated to 9000 BP was uncovered a few years back near Jacumba so aboriginals have been around the Colorado Desert for some time.

Seems like a shame to lose what they uncovered.
