Interpreted oblique aerial photograph of part of the west face of the
Guadalupe Mountains, Culberson Co.,
Texas. Note downlap of the Grayburg strata on the Cherry Canyon Sandstone Tongue as well as the major
erosional (or slump) scar which forms the contact between the bedded Grayburg shelf carbonates and the
massive Goat Seep reef. Roughly 700 m of section are exposed in this view. DLS = Downlap surface.
