Grand Teton Tours | Geological History

Stretching for more than 3,000 miles across the Western United States and into Canada stands the majestic Rocky Mountain Range. Over 55 million years old, this massive divide began its reach upward to heights of over 14,000 feet. Making up this amazing wonder are a series of smaller mountain ranges that include the Beartooth, Absaroka, and Tetons; of them all the Tetons are the youngest. Only 9 to 12 million years old, this spectacular mountain range that lies just south of Yellowstone National Park features the Grand Teton Mountain, all 13,770 feet of it. When you come along on one of Scenic Safaris’ spectacular Grand Teton tours, you will discover the beauty, wonder, and mystique of this picturesque Western wilderness.

Explore the Greater Yellowstone Ecosystem

Today, the Grand Teton area, together with Yellowstone National Park and other nearby forested areas, form what’s called the Greater Yellowstone Ecosystem, a scenic wonderland that encompasses a whopping 18,000,000 acres protected by the National Park Service. Our Grand Teton tours will introduce you to all that this fascinating and interesting geological location has to offer.

Learn the Geology of the Tetons

The Teton Range contains fault block mountains, or mountains that are formed when pressure beneath the Earth’s crust forced two pieces of land together over a fault line. These tectonic forces pushed the mountains skyward while forming a valley along one side. Although the mountains themselves are less than 15 million years old, geologists say the granite that sits at the top is some 2.5 billion years old, some of the oldest in North America. They also maintain that it was once below water and contains both marine and volcanic deposits.

As part of our guided Scenic Safaris’ Grand Teton Tours, you’ll learn about and experience the geology of this diverse area that features one of the world’s largest temperate ecosystems. Come see what this unique mountains have to offer.
