marine biologist here! where i went to school, we always called this shell hash. just a variety of old shells and bones from a variety of animals. like someone else mentioned, looks like you have a lot of old barnacle shells there.

Thank you! I watched dune buggies get stuck in six foot deep trenches of this stuff. I hung around the Salton Sea for a couple of days and saw no signs of life other than a few birds. Nobody even gets in a boat on it because the smell is nauseating.

You can find rocks made of these in the fossil record too and we call it the same thing, or sometimes “coquina” if it’s just 100% shells. It’s strange to see it being almost entirely barnacles like this though. There’s a fossil locality in Argentina near where I did my dissertation that has a couple thick intervals of pure barnacle hash like this, and it always stuck out as strange to me. It was obviously some kind of unusual event that caused the shells to all be barnacles with very little of the other shells that are usual for the area. Never did figure one out.

I was told that at one point the US Navy brought is some small ships for training on the waters there. The ships brought the barnacles. There are no natural predators for them there.

The water would rise, barnacles would start growing up to the new water mark. The water level falls, all of those barnacles die and smell really bad. There are old dead barnacle shells covering everything anywhere near the water. They are sharp and tear any bare feet right up. Not a cool place to go anymore.

Sounds like the worst breakfast option,

I know this isn’t an answer to the image, but if anyone is interested, PBS produced a really great documentary about the Salton Sea and what contributed to things like this being all over the place. And the smell… Oh god, the smell… It’s called Plagues and Pleasures on the Salton Sea.

Barnacle shells.

Pretty sure the teeth looking ones are inner shells of sea urchins.

This is odd. Where did barnacles come from in the Salton Sea?

Salton Sea is a man made lake. When first created it was stocked with fish. Things went fine for a while, but (sorry I don’t recall the reason) the water level dropped and the salt concentration rose causing hundreds of thousands of fish to die.

Accidentally man made!

If I recall correctly the water was used for crop irrigation. I need to watch the documentary.

Salton Sea used to be THE PLACE to be in its heyday. All kinds of movie stars, famous people and scores of regular people and their families used to vacation there.

Now its a gross dead lake surrounded by desert on one side and slab city on the other.

I just watched an episode of a show called Abandoned on Hulu about this lake. Tragic!

level 2

Was that the same show hosted by skater Rick McCrank? I don’t think I ever saw that episode!

At one time it was under consideration to be developed as a high end resort destination. Made Palm Springs instead. There are vacant street grids where subdivisions were underway. Now it’s the home of last resort for the homeless.

You might be thinking about slab city, but that’s an old military base.

Salton Sea is famously covered in fish bones

Fish bones I believe. I think they said in one of the documentaries.
