Grand Teton tours from Jackson Hole

Grand Teton tours tend to be confined to wildlife and scenes that you see when you drive through the main roads and back roads. We easily identify Grand Teton tours with wildlife such as moose, elk, bison, pronghorn antelope, bighorn sheep, mountain goats, bears. Sometime we are also interested in mule deer, foxes, coyote, bald eagles. Other people are interested in lodge pole pines, spruces, firs, aspens, willow trees and bushes, birch, lupine, duncecap larkspur, shrubby cinquefoil, berries, lily pads. Yet other people love the mountain bluebird, pelicans, swans, sage grouse, marmot, osprey, magpie, squirrels, beavers, otters.

The Tetons

Grand Teton tours cannot be limited to wildlife and plants. The Tetons with length of about 44.4 miles has fossilized sea creatures embedded in the rocks. Other nearby mountains may have similar ancient creatures permanently infused in them as well. Over a period of a million 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, with the rest of the mountain range is continuing to grow in height. 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. Nearly two hundred thousand years ago, glacier from Yellowstone melted over a period of thousands of years. As it did, it brought rocks and soil to the Jackson valley which was now a one mile hole deep, beside the the Tetons. Moraine from the glacier filled the hole and made it flat the way it looks today. Driving through the Tetons, you would not know a third historic event occurred perhaps half a million years ago. The earth mantle could have cracked and released basalt volcanic magma. The magma cut vertically the Tetons, at least in one place and remains as a visible dyke. There is a second intrusion that is possibly a basalt dyke as well, perhaps there are more. Grand Teton tours can be more fun with a little bit biology, scenic adventure as well as some geology.
