Yellowstone National Park is a nearly 3,500-sq.-mile wilderness recreation area atop a volcanic hot spot. Mostly in Wyoming, the park spreads into parts of Montana and Idaho too. Yellowstone features dramatic canyons, alpine rivers, lush forests, hot springs and gushing geysers, including its most famous, Old Faithful. It's also home to hundreds of animal species, including bears, wolves, bison, elk and antelope.

From trips taken in January, 2009, when only 25% of the park was open due to weather...and another trip in July of 2010...These pictures are only a tiny sample of what this amazing, amazing place has to offer...
