Yellowstone National Park

Keppler Cascades, one of many waterfalls along our road into the park.

A small part of Norris Geyser Basin.

The variety of colors in algae growing in the very hot runoff from the geysers. The color of the algae indicates the temperature of the water, green is hotter than red-brown.

Roaring Mountain.
All over the side of this hill are fumeroles (steam vents). They make a roaring sound
that can be heard for miles.

The Lower Falls of the Yellowstone River from Artist's Point.

The brink of the Lower Falls.

Bison along the Yellowstone River in the Lamar Valley.

A churning cauldron found in the Lamar Valley.

A view on the Swan Lake Flats looking toward the Gallatin Range.

Minerva Terrace at Mammoth Hot Springs.

Canary Spring on Minerva Terrace.
This was the only active spring area we saw on this very large terrace.

Black Tail Lakes in the northeast part of the park.

Yellowstone is made up of interbedded thick layers of welded Tuff and thick basaltic lava flows. The 25 foot thick basaltic flow is easy to recognize by its columnar jointing.

The falls on the Firehole River.

Hot Spring in the Lower Geyser Basin.

Patterns in the travertine formed by water flowing out of the hot springs.

Opal Pool, looking across it toward the Gallatin Range.

Old Faithful!

Fishing Cone at West Thumb on Yellowstone Lake. In the old days, you could stand on Fishing Cone, catch a fish, and cook it inside the cone.
This bay on the lake is formed in a caldera.
You can see the rim of the caldera in the distance.
