Yellowstone National Park Visit   July - August 2003 Old Faithful daytime eruption

Of about 10,000 hydrothermal features in Yellowstone, Old Faithful is by far the best known.  The geyser basin surrounding Old Faithful has wooden walkways to facilitate viewing the many fascinating thermals in the area, and a semi-circular cement walk with benches facing Old Faithful provides a safe viewing distance for the eruptions every 92 (give or take a few) minutes.  We enjoyed an afternoon eruption early in our stay, but the sky was full of puffy cloudsand the white steaming eruption sort of blended in with the clouds as you can see here.  So, we went again near  sunset another day and got a few more less cloudy photos.  See next photo.
