Bright green goop in a warm spring

Post by adamschneider » February 2nd, 2021, 9:20 pm

I was going through some old photos and found this. It's some kind of bright green slime growing in a geothermally warmed stream in Lassen Volcanic National Park, along the PCT near Drakesbad Meadow.

I want to call it "algae," but it occurs to me that this might be a plant, or it might be some sort of blue-green algae (cyanobacteria) — which is in a completely different kingdom!

Anyone know their slime?

On St Helens, I've seen warm creeks hosting the same sort of thing in vivid colors: red, yellow, orange, and of course green.

I agree with your topic title: bright green goop. Only pedants and geeks need inquire further. :geek:

It's a cyanobacterium. The components resemble something from the genus Nostoc (mare's eggs). You can see good examples in Clackamas Lake (near Timothy Lake). It's actually quite an interesting and ancient life form, especially to pedants and geeks.

You may not have thought this through.
