0 - 0.0117 Ma
Age: Anthropocene (0 - 0.0117 Ma)
Description: White, gray, and light-red, fine- to medium-grained, well-sorted quartz sand accumulations that are aligned in general northeast direction. Commonly transitional with other eolian surficial deposits (Qd, Qes, Qdp, Qdb). Linear dunes generally are 12 to 24.5 m (40 to 80 ft) wide and less than 0.8 km (0.5 mi) long, but they can extend over 5 km (3 mi) or more in length on Ives and Marcou Mesas. Thickness, 2 to 9 m (6 to 30 ft)
