In structural geology, a syncline is a downward-curving fold, with layers that dip toward the center of the structure. On a geologic map (or "in map view"), synclines are recognized by a sequence of rocklayers that grow progressively younger, followed by the youngest layer at the fold's center or hinge, and by a reverse sequence of the same rock layers on the opposite side of the hinge. If the fold pattern is circular or elongate circular the structure is a basin. A notable syncline is Wyoming's Powder River Basin. Folds typically form during crustal deformation as the result of compression that accompanies orogenic mountain building.

There is usually water in Syncline Valley, 3.4 miles from the trailhead, but it must be purified before drinking.
There isn't as much water in the upper part of Syncline Valley as in the lower part, but it is still a green oasis in the desert canyon country.
Hidden as it is from the outside world, Syncline Valley is the kind of place that would have made a perfect hideout for a band of outlaws at the turn of the century.
A syncline is a fold in which the youngest rocks occur in the core of a fold (i.e., closest to the fold axis), whereas the oldest rocks occur in the core of an anticline.
In structural geology, a syncline is a downward-curving fold, with layers that dip toward the center of the structure.
On a geologic map (or "in map view"), synclines are recognized by a sequence of rocklayers that grow progressively younger, followed by the youngest layer at the fold's center or hinge, and by a reverse sequence of the same rocklayers on the opposite side of the hinge.
