Once upon a time, Upper Grinnell Lake didn't even exist. Instead, the
Grinnell Glacier covered the entire area where the lake now is, along
with covering the area where I'm standing as well as all those weird
rock formations are on the right. However, the warming climate has taken
a heavy toll on the glaciers in
and the Grinnell Glacier is no exception. Only 40% of the Grinnell Glacier
remains. Taking its place, by filling in the depression left by the retreating
glacier, is Upper Grinnell Lake. The rather odd "ridged" rock
formations you see in this photo were created by the movement of the
glacier and which, due to the glaciers melting, is now exposed.
