More pond(erings) in Yellowstone

Octopus spring, famous for its white sediments around its edges. Also, there is an elk skeleton in the bottom that has been there for over 8 years. This spring is not acidic, so the skeleton last longer than in the springs with a ph of 2-3 or so.
Mushroom Spring, the source of Thermus aquaticus, a bacteria that gave us the TAQ enzyme, which has revolutionized PCR and molecular biology. This is the source of the Nobel Prize!
Grand Prismatic Spring, a large, hot pool surrounded by orange bacterial mats.
Lake Yellowstone, a large cool lake that is in the old caldera remnant of the volcano that blew up here 600 000 years ago. Under the surface there are hot vents where magma-heated water squirts out into the cool lake water. Many people have drowned on this lake too.

PCR? photo chemical reaction?
Pointless corrective rain?
painless current reconstruction?

Post-Crash Regrets?
Posting Craziness Repercussions?
Pointless Characters in a Row?

I like your pictures, but I am having a very hard time understanding how they sit in the landscape. I can't tell the scale of things...do you have some that show more of the scene?

Yep, next post will only be landscape pictures! Grand vistas! I guess I have only focused on the small so far, not the giant.

PCR - Polymerase Chain Reaction, a way to make a million copies of one tiny bit of DNA inside a test tube. We use the method all the time. But I like your abbreviations much better, especially "Pointless Characters in a Row"!
