The Northeast Entrance road passes thru beautiful Lamar Valley, with views of the Absaroka Mountains towering above you. Soda Butte is a terrace of calcim carbonate and was formed by hot water dissolving the underlying limestone and bringing it to the surface.
The East Entrance Road passes thru some of the most beatuiful alpine scenery in all of Yellowstone. The entrace is at 7,200 feet and the road climbs to 8,541 feet. Sylvan Lake is a popular stop along the East Entrance Road.
The South Entrance to Yellowstone leads from Grand Tetons National Park and the Rockefeller Memorial Parkway. A short distance from the south entrance is Moose Falls. Here Crawfish Creek tumbles down from the plateau toward the deep canyon of the Lewis River. Lewis Falls is another beautiful spot as it plunges 37 feet.
Here at Mammoth Hot Springs, water doesn’t erupt like in the geyser basins but flows, gently from cracks. Hot water dissolves the underlying limestone and
deposits it on the surface forming these huge terraces. As we leave Mammoth Hot Spring heading south, the road passes thru Golden Gate. The road passes byObsidian Cliff, a “mountain of glass”. This rock formation is the same as rhyolite, but in this case, the rhyolite cooled so quickly that it did not crystalize. Instead, black glass was formed.
Much of this section follows the beautiful Yellowstone River. The Mud Volcano are contains many interesting thermal features. Shown here is the Dragons Mouth.
A short hike leads to the Dragons Mouth and Sizzling Basin. One of the best spots in all of Yellowstone – Hayden Valley. This is a good place to see Bision, Coyotes, and Bear.
Beautiful Yellowstone Lake is the largest at this high of an elevation. It is 20 miles long and 14 miles across and covers an area of 139 square miles. It has an average depth of 137 feet with the maximum depth being 320 feet.
