Silver Gate - Travertine

Detailed Description

On the drive south of Mammoth Springs, you pass through Silver Gate which is a landslide deposit of travertine stone at least 400,000 years old. 

Silver Gate landslide complex in Yellowstone National Park. The jumbled nature of the calcium-carbonate rocks is evidence that the deposit was formed by the collapse of a travertine hot-spring terrace that might once have looked like Mammoth Hot Springs does today.
