Abstract

This study focuses on desert pavement in Panamint Valley, just west of Death Valley, California, and documents the healing of surface scars showing that clast displacement is an essential element of pavement integrity and longevity. Human disturbance to the pavement cover, if not too extensive, can also be repaired by this mechanism. The cross-surface flux of stones also represents a powerful smoothing agent, lowering topographic highs and filling topographic depressions. The results presented here support a recent model of pavement formation on volcanic flow surfaces that emphasizes the importance of dust-accretion over deflation
