This gigantic glacial cirque formation is seen from Glacier National Park's "Going to the Sun Road".
The beginning cirque process is called "nivation", where a hollow in a slope is enlarged by glacial erosion and weathering. Ice segregation erodes the vertical rock slope and its disintegration often includes avalanches bringing down more snow and rock to add to the growing glacier. Debris within the ice also abrades the bed surface and eventually the hollow becomes a large bowl, or amphitheater in the side of the mountain.
Global warming has impacted the National Park's glaciers. In the mid 19th century there were 150 glaciers here. Today only 25 active glaciers remain. Scientists predict they all will disappear by 2020 at the current warming rate.

Hello Ray, great view of the rock formation carved by ancient glaciers. Great quality and sharpness throughout. Your notes explain some chilling facts about global warming and perhaps someday people will ask why they named that park Glacier Nat. Park when the glaciers have all recede.

Las Vegas is a favorite stopover for egrets, pelicans and other migratory birds during migration.

The natural curves in this are cool, and I cannot help but picture wile e coyote trying to roll a boulder off one side only for it to roll dowm up and back to squash him. Sorry, I know that's a childish view, but p it's the first thing that sprang to mind :) the trees give a brilliant sense of the sheer size of this too. Really nice composition.
All the best

Look, a natural amphitheater! I bet you it was built much earlier than the ones from the Greco-Roman world, too! I love your composition, it brings out the majesty of this corner.
