Yellowstone National Park, Lake Area - 8/16/14

Today was our third visit to Yellowstone and we saw the following amazing portions of the park:
  • West Thumb Geyser Basin
  • Yellowstone Lake area
  • LeHardys Rapids
  • Mud Volcano area
  • Wildlife in Hayden Valley
West Thumb Geyser Basin:  This area overlooks beautiful Yellowstone Lake, the largest lake above 8,000 feet elevation in North America. About 174,000 years ago, a volcanic explosion created this basin with various hydrothermal features. The geyser basin pours 3,100 gallons of hot water into the lake daily, but the average summer temperature of the lake remains 45 degrees.

See the steam rising from the lake?

Fishing Cone. Fisherman used to stand on this cone, catch a trout, drop it in the boiling water of the geyser, thereby cooking it before taking the fish off the hook! Today, fishing is prohibited from it.

Yellowstone Lake: Some facts about this huge lake.
  • Elevation = 7,733'
  • Area = 132 square miles
  • Shoreline = 141 miles
  • Width and length = 14 miles x 20 miles
  • Depth = average is 140'; deepest is 410'

Sautéed Trout and salad.

LeHardys Rapids (on the Yellowstone River north of Yellowstone Lake).





Mud Volcano area:  Some of the most acidic hydrothermal features in the park are found in this area (and the pungent smell is pretty intense!)  Loud rumbling sounds caused by steam can be heard at Dragon's Mouth Spring as water crashes against the walls of a hidden cavern.


Mud Volcano:  In the 1870s, there was a large cone (30' x 30') with mud erupting to cover tall trees. A violent eruption blew away one side of the cone, leaving this.

Sour Lake.

Sulphur Caldron is as acidic as car battery acid (or stomach fluids). The bubbling is caused by carbon dioxide and other gases rising from below and heat.


Hayden Valley:  Driving through the valley in late afternoon, we were so lucky to see a very large herd of bison on both sides of the road. They casually lumbered across the road whenever they felt like it. It was amazing to behold these majestic animals in the wild.
