One of two pans of Horseshoe Bend, a lovely incised meander near Page, Arizona (just southeast of Glen Canyon Dam). Erosion by the Colorado River cut down through the layers of sedimentary rock and created the deep gorge (approx. 1000 feet deep here). The river meander, though, formed by the same processes that for...

Now geolocated, this is a turnout that looks over Midway Geyser Basin (the famous Grand Prismatic Spring would be off to the right in the distance). Very few people seemed to be stopping to look here, which is why we pulled over. Nice place to view run-off from the geysers entering the river (believe this is the Fi...

Some nice sets of crossbeds (angled sedimentary bedding) in sandstone (Wahweap formation, according to my field notes). The angled beds formed in a sand dune, most likely, that is preserved now in the rocks. The compass is for scale...

View of the Tetons from Oxbow Bend - the Snake River visible in the foreground, the Tetons in the far ground. (There's a rather famous Ansel Adams photo that's taken from near this location. It's almost as if all photographers feel a subconscious urge to take a photo at this spot, I think...)

From the Devil Canyon overlook, looking north along the main channel of Bighorn Canyon. If I remember the stratigraphy correctly, the top layer of the canyon is formed from the Madison Limestone, which is over 350 million years ago - same age and similar in appearance to the Redwall Limestone that makes up part of t...

That's the name given to this particular overlook along Rte. 12 in southern Utah. Large expanses of Navajo Sandstone make up the majority of the foreground rocks - these were once (millions of years ago) a vast expanse of sand dunes. The remnants of the dunes are found in structures called cross beds, where layers of...

Across the street from the scenic overlook "On a Clear Day You Can See Forever" (www.gigapan.org/gigapans/32030/) is this particular outcrop, which is a really nice view of cross beds. These structures are remnants of sand dunes (millions of years old, now preserved in the sandstone rock).

At the end of the geyser walk starting near Old Faithful is Morning Glory Pool - named for it's deep color, which has faded over time due to objects thrown in the pool by visitors (these can block the pathways the hot water takes to the pool). The different colors are due to different micro-organisms (bacteria, arch...

Colloquially called 'the blues' because of the blue-grey color, these sedimentary rocks outcrop in a canyon along Rte 12 in southern Utah. The blue-grey rocks are part of the Cretaceous Kaiparowits formation, which formed when large rivers deposited their sediment. The orange layers in the distance are made up of...
