Featured photo Summer 2024

Sunset, eastern Grand Canyon, August 2013.  View is to the southeast from Point Imperial.   Multiple planes of the exposed layers from foreground to the distant cliffs show views of horizontal strata of Paleozoic age overlying deformed Precambrian strata. The contact between the deformed and horizontal strata is referred to as the “Great Unconformity” that represents a time gap of nearly a billion years.   

Shortly after this photo was taken the moon rose over this region, as seen in this photo and in the sequence shown here.

 

The Eastern Grand Canyon region was also viewed from the air in Feb. 2010, as described here.
