Geology of Tetons & Yellowstone
Geology of Yellowstone and geology of Grand Teton Park are fascinating. For instance, the Grand Tetons have fossilized sea creatures embedded in few places. You could find such phenomena in Yellowstone as well. Some of our guides will talk about Yellowstone Geology if that is what interests you. Over a period of millions of years, the Tetons began to experience tectonic movements which have continued to this day. The mountains would have been part of a sea or perhaps ocean floor. The Grand Teton at 13,800 feet is believed to increase in height gradually, with the rest of the mountain range. While the Tetons rose , the Jackson valley from the town of Jackson to Moran experienced gradual sinking. When you drive from Jackson to Snake River Overlook, you wonder why the land is flat. That is why Geologic tours of the Grand Tetons and Yellowstone are fascinating indeed.
