Although the weather had been extremely cooperative up to this point, today was the inevitable cloudy, overcast, rainy day. Not great for pictures, but since my dad says a good photographer should be able to shoot in any light, we gave it a shot anyway.
(Liberal use of Picasa's touch-up features helps too)
Yellowstone Canyon is pretty impressive, what with the sulfur-colored walls and all. We also got a chance to take a few "moderately strenuous" hikes to get some views of the falls. In one case, this hike consisted of ~300 stairs (yay!). Compounding that was the realization that the elevation is about 6000 ft, which made me feel REALLY out of shape. On the plus side, this time of year the park is filled with mostly retirees, so by comparison I felt like a marathon runner.
