A Great Unconformity

I almost forgot our quick side trip at the end of the day. With the Green River Formation behind us (literally, in this photo), we turned to view a fantastic example of an angular unconformity here in central Utah. Although there are several significant unconformities in the area, this unconformity is probably my favorite, because it shows paleotopography as you follow it regionally from west to east.

The photo above shows the unconformity that places the Paleogene Colton Formation on top of the vertical Jurassic Twist Gulch Formation.
