Yellowstone! Old Faithful
I already shared the close up shot of Old Faithful. We arrived at the lodge, after about 30 minutes of looking for parking, just in time, according to the geyser clock in the lobby, for the next eruption, and made it out to the nearest corner of the boardwalk with seconds to spare. It does not matter how many times you see it, or how many photos or videos you see, there is nothing like being there. One second the mound of colored rock is all there is to see, and the next, after a tentative spurt of steam or two, there is a column of boiling water and steam 130 feet (or more) tall. The roar. The rush! I barely had time for a few shots with the a6700 and the Tamron at 75mm equivalent…and then to switch to the a5100 and E 10-18 f4 at 27mm equivalent, which you see here.

Yellowstone! Mud Volcano
Seeing the grand sweep of the mountains of Yellowstone, or the vast waters of Yellowstone Lake, it is hard to remember that you are standing on a thin crust over one of the largest magma chambers of one of the largest super volcanos in the world. Two active magma domes under the park inflate and deflate on a long cycle, actually tipping the landscape in real time…changes that can be, and are being, measured. Then you come up on one the hydrothermal areas beside the road: bubbling hot springs and travertine domes and terraces, geysers blowing superheated water high into the air, or as here, steam rising from super heated, boiling mud…and the volcanic nature of Yellowstone becomes that much more real. The thickness of the crust of rock over the magma domes still is measured in miles…as little as 3 or as much as 12…but there are few areas in the world where the crust is so thin. Old Faithful may be impressive, and justly well known because it is, but it the sheer number of hydrothermal features in Yellowstone that is the most impressive.
