摘要: Military activities cause physical alteration of landscapes that can provide geomorphologists unique opportunities to better understand natural processes. Today’s desert pavement in western Arizona exhibits scars from 1940s era tracked vehicle maneuvers. This study examines the impact these military maneuvers with particular attention an unexpected field observation deeper soil moisture penetration beneath scarred than under undisturbed pavement, a condition appears contradictory results previous work. Field work and backscatter electron microscopy images reveal destruction Av horizon fractured plasma near surface track scars; this fracturing promotes relative naturally indurated, compact, material pavement. Increasing subsurface may encourage plant growth have consequences ecological functioning largely barren
