The NE ridge of the Dagout Mt. ridges contains
Wolfcamp which swings about in strike
to about N80°E. — This I would judge
as a change from about N60E (to the SW).
Oh for some photographs.
The Gaptank goes through some beautiful
folds and contortions. The small folds
and faults near the top of the Gaptank
I feel are good evidence for the extent of thrusting.
