Canyonlands National Park
One Park, Four Districts, Endless Possibilities
Canyonlands National Park preserves 337,598 acres of colorful canyons, mesas, buttes, fins, arches, and spires in the heart of southeast Utah's high desert. Water and gravity have been the prime architects of this land, sculpting layers of rock into the rugged landscape you see today.
Canyonlands preserves the natural beauty and human history throughout its four districts, which are divided by the Green and Colorado rivers. While the districts share a primitive desert atmosphere, each retains its own character and offers different opportunities for exploration and adventure.
Though they appear close on a map, there are no roads that directly link the districts. Traveling between them requires two to six hours by car as there are few places to cross the rivers. Get directions. Most people find it impractical to visit more than one area in a single trip. Use the maps and links below to get some ideas on places to go. (National Park Service)
Canyonlands National Park: Island in the Sky map
After arriving at Salt Lake City International Airport (KSLC), We drove down to Canyonlands National Park. First stop was at the Island in the Sky Visitor Center for my National Parks Passport Stamp! Then we drove down to Green River Overlook and Upheaval Dome. We did the Upheaval Dome to first overlook Trail (0.6 mi).
”Canyonlands is a place of relative geologic order. Layers of sedimentary deposits systematically record chapters in the park's past. With some exceptions, these layers have not been altered, tilted or folded significantly in the millions of years since they were laid down by ancient seas, rivers or winds.
Upheaval Dome is quite a different story. In an area approximately three miles (5 km) across, rock layers are dramatically deformed. In the center, the rocks are pushed up into a circular structure called a dome, or an anticline. Surrounding this dome is a downwarp in the rock layers called a syncline. What caused these folds at Upheaval Dome? Geologists do not know for sure, but there are two main theories which are hotly debated.
Salt Dome Theory
A thick layer of salt, formed by the evaporation of ancient landlocked seas, underlies much of southeastern Utah and Canyonlands National Park. When under pressure from thousands of feet of overlying rock, the salt can flow plastically, like ice moving at the bottom of a glacier. In addition, salt is less dense than sandstone. As a result, over millions of years salt can flow up through rock layers as a "salt bubble", rising to the surface and creating salt domes that deform the surrounding rock.
When geologists first suggested that Upheaval Dome was the result of a salt dome, they believed the land form resulted from erosion of the rock layers above the dome itself. Recent research suggests that a salt bubble as well as the overlying rock have been entirely removed by erosion and the present surface of Upheaval Dome is the pinched off stem below the missing bubble. If true, Upheaval Dome would earn the distinction of being the most deeply eroded salt structure on earth.
Impact Crater Theory
When meteorites collide with the earth, they leave impact craters like the well-known one in Arizona. Some geologists estimate that roughly 60 million years ago, a meteorite with a diameter of approximately one-third of a mile hit at what is now the Upheaval Dome. The impact created a large explosion, sending dust and debris high into the atmosphere. The impact initially created an unstable crater that partially collapsed. As the area around Upheaval Dome reached an equilibrium, the rocks underground heaved upward to fill the void left by the impact. Erosion since the impact has washed away any meteorite debris, and now provides a glimpse into the interior of the impact crater, exposing rock layers once buried thousands of feet underground.” (National Park Service)
After that we drove down to Buck Canyon Overlook & Orange Cliffs Overlook.
***As of this writing, Grand View Point Overlook, Grand View Point Trail, and 0.3 mi (0.5 km) of park road will close 6 am Mondays to 4 pm Thursdays for a total of eight weeks. The closure applies to all uses, including vehicles, tour buses, motorcycles, bikes, & hikers.***
