The Sonsela Member of the Chinle Formation in the Chinle Valley

This is how I spent my fourth of July, checking out Sonsela Member outcrops throughout the Chinle Valley:

Sonsela Member outcrops.  The Chuska Mountains in the background.
In-situ petrified log in the upper portion of the member.

Another log at the same horizon. Round Top Ridge (left) and Round Rock (right) in background, the Petrified Forest, Owl Rock, and Rock Point Members of the Chinle, and the Wingate Sandstone.

The Sonsela Member is predominantly a sandstone interval.

In-situ petrified log on cliff top.

View of a portion of the Chinle Valley from ledge south of Round Rock at the end of the day.  The Sonsela Member is the grey swath across the upper center of the photo, the red is the Petrified Forest Member.
