A Walk Through Time: Gardner Canyon Geology
Karen Williams, Ph.D.
The north entrance of Yellowstone is a complex geologic area. Glaciers from the Gallatin range, the Yellowstone ice cap, and the Beartooth plateau interacted in this area during the last Ice Age creating glacial landforms and periodic glacial outburst floods. In addition to the glacial story, this area has been subject to folding and faulting, landslides and earthflows, and most recently the 2022 floods. In this field seminar, we will travel off trail along the edge of the Gardner River Canyon starting near Mammoth and past Slide Lake observing landforms and geologic units exposed in the canyon and hiking over landforms created by landslides and earthflows. We will make a large loop returning to Mammoth via trail.
