piedmont slope


piedmont slope
   (colloquial: western USA)
   The dominant gentle slope at the foot of a mountain; generally used in terms of intermontane-basin terrain in arid to subhumid regions.
   Main components include:
   1) An erosional surface on bedrock adjacent to the receding mountain front (pediment, rock pediment);
   2) A constructional surface comprising individual alluvial fans and interfan valleys, also near the mountain front; and
   3) A distal complex of coalescent fans (bajada), and alluvial slopes without fan form. Piedmont slopes grade to basin-floor depressions with alluvial and temporary lake plains or to surfaces associated with through drainage (e.g., axial streams).
   Compare: bolson, fan piedmont.
