Kayenta Sandstone Caprock in Colorado National MonumentColorado National MonumentMay 22, 2007. There are several campgrounds available in the Fruita / Grand Junction area. We chose Monument RV-Park just because we needed to easily & quickly get into the campground and head out to experience Colorado National Monument. Monument RV-Park is a good clean park but at at $35 price tag. They do have location ---- like, within a mile of the western entrance to Colorado National Monument. The Colorado River State Park is located directly across the street from Monument RV-Park. I think we would probably stay in the State Park on a return trip if for no other reason than cost.
Colorado National Monument
We arrived in Fruita today expressly to tour Colorado National Monument. The Colorado National Monument isn't one of the "top-10" destinations for tourist but it is one of the most spectacular drives you can take. The views and geology exposed in the monument are some of the best available.
Kayenta Formation caprock protecting Wingate Sandstone Colorado National Monument
As we climb we are going through layer upon layer of sedimentary rock exposing 100s of millions of years of geology. As we climb remember that the rock layers are becoming younger and younger.

Colorado National Monument, is not a National Park but most people do not know the difference between a National Park and a National Monument. A national park is established by an act of congress, and usually applies to a site that is nationally-significant in multiple ways. A national monument, on the other hand, is established by presidential proclamation, and usually applies to a site that is nationally significant, but for a singular reason.

In this exposure of Wingate Sandstone you can see desert varnish the dark coating that coats many desert walls.
Kayenta Formation is the caprock protecting the softerWingate Sandstone beneath the caprock
Sandstone weathers into unusual shapes. Here a ridge between two canyons is eroding into a series of domes. The key factor in shaping these adjacent monoliths is the upper layer of harder rock (Kayenta Formation). This caprock layer is breakable, but resistant to erosion. Where the cap layer remains, the softer rock (Wingate Sandstone) beneath is protected; where it has broken away, the underlying formation has rapidly eroded to a rounded form.

With the relatively resistant Kayenta Formation "caprock" intact, cliffs remain tall and fairly flat-topped. Only minor erosion occurs along vertical cracks. A single hoodoo is forming on the left side of this picture.
How Kayenta caprock protects the Wingate Sandstone
When the Kayenta formation camprock is eroded off, underlying Wingate Sandstone begins to erode from the top down, forming more rounded spires and dome shapes.
You can certainly see how the hard Kayenta "caprock" protects the Wingate Sandstone in these pictures. The funky domed shaped formations are referred to as hoodoos.

How many years will it take for these formations to take on the dome shapes of the formations above? But even a novice can see how the harder Kayenta formation caprock protects the softer Wingate Sandstone. Look closely and you can see where hoodoos are beginning to form in areas where the caprock is no longer in place.

This is Red Canyon on the eastern side of Colorado National Monument. This view is looking north into the valley and Grand Junction, Colorado in the distance.

Joyce took this picture of Grand Junction, in the valley and an awesome switchback visible several hundred feet below as we snake our way down the cliff face on the eastern side of Colorado National Monument.
