The Wind River Pinnacle is commonly known as Chimney Rock.
|

Wind River Canyon is a spectacular canyon three miles south of Thermopolis on Highway 20.
|

The highway through the Canyon was one of the most difficult and expensive roads constructed in the West, at a cost of $700,000. It was opened January 1924.
|

The Canyon is 13 miles long. As you enter the canyon from the north, the red cliffs are only 300 feet above he Wind River.
|

The Canyon is a geologist’s dream because so many layers of ancient rocks are clearly exposed – from lower level Precambrian age (1.5 billion years) to top-level Mesozoic (250 million years).
|

The angles of sediments show uplifting and movement, the result of the rise of what would become the Rocky Mountains.
|

The Canyon is home to a variety of animals, ranging from small chipmunks to big horn sheep.
|

The Canyon walls demonstrate molten lava stages, the rise of mountains that twisted the layers, as well as evidence of an inland ocean, with beach and ocean sediments.
|

Further into the canyon, canyon walls rise to 2600 feet.
