a: lake bottom ~
b: a natural mummification system
What:
"Since this lake is meromictic, its surface waters do not mix with salty anoxic (lacking oxygen) waters below. Anything that falls to the bottom will meet a massive collection of debris, and decays so slowly that researchers are able to take core samples and find out what plants and animals inhabited the area thousands of years ago. The lake bottom is like a natural mummification system."
