Feasting in Fossil Lake
Topping the high ridges that surround us are
rock layers formed from sediments deposited
on the bottom of Fossil Lake about fifty
million years ago.
The lake and its encircling mountains basked in
sub-tropical sunshine and bathed in torrential
rainstorms. Sometimes the lake overflowed.
When its waters returned, loaded with organic
nutrients, the algae bloomed.
These abundant crops of algae furnished the
food essential to sustain the lake's species-
diverse food chain.
