From Glaciers to Canyons: The Geologic Story of Rocky Mountain National Park

Rocky Mountain National Park, located in the north-central region of Colorado, covers an area of 415 square miles and is one of the most visited national parks in the country. Its unique landscape is a result of geological processes that occurred over millions of years. Let’s take a closer look at the geologic story of Rocky Mountain National Park.

Geological History

The formation of the Rocky Mountains began about 70 million years ago during the Laramide orogeny, a period of intense mountain building in western North America. The forces of tectonic plates moving and colliding pushed up layers of sedimentary rock, creating a range of steep peaks and deep valleys.

Over time, the mountains eroded and created vast plains. But around 30 million years ago, the region experienced volcanic activity. Lava flows covered the area, and extensive tectonic activity caused the Rocky Mountains to lift even higher.

Eventually, the Ice Age began, and glaciers formed in the mountains. They carved out valleys, lakes, and canyons, leaving behind the glacial moraines and boulders that can be seen today.


Rocky Mountain National Park’s unique mixture of mountain, glacier, and volcanic activity has created an incredibly diverse landscape. Visitors to the park can see towering peaks, glaciers, and canyons, as well as alpine lakes, meadows, and forests.

One of the park’s most famous features is Longs Peak, the highest point in the park and one of the highest in Colorado. At 14,259 feet above sea level, it offers a challenging climb for experienced mountaineers.

Other notable features include Bear Lake, which sits at the end of Bear Lake Road and is surrounded by hiking trails. The park also includes the gorgeous Trail Ridge Road, a scenic drive that goes above the tree line and offers views of the surrounding peaks.

There are many great hiking trails in the park, ranging from easy nature walks to challenging backcountry treks. Notable trails include the Emerald Lake Trail, the Chasm Lake Trail, and the Flattop Mountain Trail.

Rocky Mountain National Park’s geologic story is one of intense mountain building, volcanic activity, and glacial erosion. Its unique landscape is a testament to the power of natural forces over millions of years. With so much to explore and discover, it’s no wonder that so many visitors come to this incredible national park each year.
