Geology of Dead Horse Point State Park

Discover the breathtaking landscapes of Dead Horse Point State Park in Southern Utah. Located just southeast of Moab, this natural wonder is a must-visit destination.

You'll encounter a fascinating range of rock formations as you explore the park. From the ancient Kayenta Formation at the top, dating back 184-188 million years, to the historic Cutler group at the bottom, which formed 270-285 million years ago. These sedimentary layers offer a glimpse into the diverse environments that existed in the past, from oceans and deserts to lakes, streams, and floodplains.

While most of the rocks visible from Dead Horse Point are sedimentary, there are also intriguing igneous and metamorphic formations to be found. Take the La Sal Mountains, for example, which are of igneous origin and add a touch of majesty to the landscape. And let's not forget about the metamorphic rocks, altered by the immense heat and pressure within the Earth's depths.

The Colorado River has played a significant role in shaping this magnificent terrain over time. Carving its way through the rock layers, it has unveiled the stunning formations we see today.

But the wonders of Dead Horse Point State Park don't end with the rock formations. Surrounding the park, you'll be captivated by the Tertiary La Sal, Abajo, and Henry Mountains. These majestic peaks, which rose from deep within the Earth 48 to 25 million years ago, are composed of diorite. Erosion over millions of years and the sculpting touch of glaciers during the last glacial maximum have created the awe-inspiring jagged peaks and valleys that make this area truly unforgettable.

The geological history of Dead Horse Point State Park also includes a wealth of fossils. You can find them in the sedimentary layers, where evidence of prehistoric creatures from millions of years ago is preserved. These fossils offer a rare glimpse at what life was like before man existed and provide insight into the ancient environments that once existed in this area.

At the very top of Dead Horse Point State Park, you'll find the Kayenta Formation. This layer of sedimentary rock is estimated to be 184-188 million years old and covers over 2,200 miles in Utah alone. The fossils preserved here provide a fascinating glimpse into the ancient marine environment that existed in this region millions of years ago.

Wingate Sandstone can also be found in the park and dates back to the Triassic period. This sandstone was formed in an ancient desert and is composed of a variety of sedimentary materials, including quartzite. As you explore this area, you'll find interesting features such as natural bridges and arches carved out by water over millions of years.

The Chinle Formation can also be seen at Dead Horse Point State Park. This distinctive layer was formed in a desert environment that existed around 220 million years ago. The bright red, orange, and yellow colors indicate that this area has been exposed to extreme temperatures for an extended period of time. Throughout the Chinle Formation, you'll find petrified wood and fossilized leaves that tell a story of what life was like in this area millions of years ago.

You'll find the Moenkopi Formation at the bottom of Dead Horse Point State Park. This reddish-brown layer dates back to 270-285 million years ago and is composed of siltstone, sandstone, shale, and limestone. Its fascinating features provide evidence of ancient lakes, streams, floodplains, and wetlands that once existed here.

The Cutler Group is located at the very bottom of the park and dates back 285-300 million years ago. This sedimentary deposit contains rocks such as limestone and sandstone, which were formed in an ancient marine environment. You'll find interesting features here that provide evidence of life forms from millions of years ago.

The White Rim Sandstone is also quite prominent in the park. This distinctive rock layer was formed in an ancient desert and dates back to around 200 million years ago. Its bright white color indicates that it has been exposed to extreme temperatures for a long period of time. This sandstone is full of fascinating features, providing insights into this area's geological past.
