My family & I, took an adventure trip, to Yellowstone, July 2010. After 2 weeks spent in the park, I brought home plenty of pictures, here are a few examples. The whole Park is actually the bowl of a dormant super volcano. It has 70% of the worlds geysers, It abounds in hot springs, pools,mudpots & fumeroles ( steam vents ). The park also has an abundance of wild animals & birds, a most memorable trip indeed.
