I've shown the original photo again, below, with major geologic units and contacts added to the duplicate photo below that. It turns out that the central portion of the area, which is the somewhat bowl-shaped Richardson Ampitheater, is underlain by the dark red Permian Cutler Formation, and that red and red-orange Triassic to Jurassic formations make up most of the rest of the picture back to about where I've drawn the Dakota Sandstone, which is Cretaceous.
Please note that the contacts between formations, especially between the Permian Cutler Formation and the Triassic Moenkopi Formation, are inexact. Additionally, the contacts between the Wingate Sandstone, Kayenta Formation, Navajo Sandstone, and Entrada Sandstone are inexact, possibly mislocated in some places on the photo, and more complex than shown. Generally speaking, I've left out the Kayenta Formation between the Wingate and Navajo formations, and have only shown a few formations above the Entrada Sandstone for some semblance of simplicity. Do not rely on my lines for any kind of mapping in the area other than crude, for-fun stuff; instead, go to the original sources!
For precise geologic details, please see the three geologic quadrangle maps of the area, the Fisher Towers quadrangle, the Big Bend quadrangle, and the Dewey quadrangle, also referenced below. Other nearby geologic maps can be found here. I noticed geologic explanations and descriptions of map units (map legends) only on the second and third of the above quadrangles. Another, smaller-scale map, covers the entire area, the geologic map of the Moab and eastern part of the San Rafael Desert 30' x 60' quadrangles. To follow along with the general stratigraphy of the area, see the strat column below for nearby Arches National Park.

And hey, now for some photos! Above you can see the famous Fisher Towers, with the semi-frozen Colorado River in the foreground and the La Sal Mountains in the background. The photo was taken from Route 128 looking almost directly south, before getting into Professor Valley and the Richardson Ampitheater. For another excellent and similar view of the towers - without snow - see this post at Geotripper, which also describes the Moenkopi Formation.
Fisher Towers is an awesome place, in my opinion, located on the east side of the Richardson Ampitheater. The towers are capped by the lower part of the Triassic Moenkopi Formation above the Permian Cutler Formation, which forms almost everything you see in the above photo, from the Moenkopi cap down. This view of the towers was taken from the red-dirt access road to Fisher Towers, looking more-or-less to the east.
From the towers, you can look all around the area, with the cliffs and towers behind you, and a grand 180-degree plus view in every other direction.
A closeup of part of the mesa shows the unusual rock formations in more detail. The pillars to the right of the central Wingate Sandstone cliff are called the Priest and Nuns, with the large man-like figure presumably being the priest. The larger pillar to the left of the Wingate cliff is called Castle Rock, and sometimes called Castleton or Castleton Tower. Perry, of Robert Perry Hooker, provided a link to a fabulous panorama taken from the top of Castle Rock.
Also, as mentioned in earlier comments, Jon Bon Jovi shot a video from the central Wingate mesa seen in the previous photo (and from Castle Rock?). The video is for his song Blaze of Glory. Castle Rock, the Priest and Nuns, and Fisher Towers can occasionally be seen in the video, along with other panoramas of the area.
