|Quaternary surficial deposits, undivided|
Age: Pleistocene (0 - 2.588 Ma)
Description: Unconsolidated to strongly consolidated alluvial and eolian deposits. This unit includes: coarse, poorly sorted alluvial fan and terrace deposits on middle and upper piedmonts and along large drainages; sand, silt and clay on alluvial plains and playas; and wind-blown sand deposits. (0-2 Ma)

|Dune sand and sand-sheet deposits|
Age: Anthropocene (0 - 0.0117 Ma)
Description: Hopi Buttes area (sheet 2): Light-red and white, fine-grained quartz sand; locally derived mainly from other surficial units whose sediments are easily eroded by wind (Qs, Qf, Qf1, Qf2, Qf3, Qg1, Qg2, Qg3, Qa1, Qa2, Qa3, Qae, QTdi). Originally those sand grains were derived from erosion of nearby bedrock outcrops of the Moenave, Kayenta, and Bidahochi Formations and include fragmented grains of volcanic rock (Tm, Tmt, Tmu). Forms lumpy, undefined sand-dune or sand-sheet deposits often concealed beneath moderate growths of grass, sagebrush, and pinyon pine and juniper woodlands at higher elevations of volcanic mesas and buttes. Little Colorado River area (sheet 1): White to light-red, fine- to coarse-grained, windblown sand; composed primarily of quartz, chert, and some feldspar grains locally derived from other surficial deposits eroded by wind (Qs, Qf, Qf1, Qf2, Qf3, Qa1, Qa2, Qa3, Qg1, Qg2, Qg3, Qae). Contacts are approximate and subtly gradational with adjacent alluvial deposits and bedrock and are likely to change on yearly basis under influence of variable weather conditions such as strong windstorms and sheet-wash erosion associated with local severe thunderstorms. Locally includes topographically controlled climbing and falling sand-dune and sand-sheet ramp accumulations on gentle slopes or steep bedrock terrain northeast of Little Colorado River Valley. Contacts between young sand-dune and sand-sheet deposits (Qd, Qes) and old sand-dune and sand-sheet deposits (QTd, QTes) are difficult to constrain by empirical observation but, as mapped, show boundaries that illustrate potential differences between young and old sand accumulations on Ives Mesa, on Marcou Mesa, and in some areas of Hopi Buttes. Supports moderate growths of grass and high-desert shrubs that help stabilize all eolian-sand accumulations during wetter conditions. Thickness, 1 to 61 m (3 to 200 ft)
