Figure 34-35 morph.
Structure produced by sinuous, out-of-phase bedforms; eolian deposits in the Navajo Sandstone (Upper Triassic? and Jurassic) near Snow Canyon, Utah. Dark spots on the outcrop are bushes approximately 1 m high. This structure is a close approximation of the computer-generated structures formed by bedforms with out-of- phase plan-form geometries.
