Glaciation and Periglacial Morphology in the Northwestern Venezuelan Andes

Carlos Schubert
Evidences of previous glaciation in the northwestern Venezuelan Andes, mainly in Páramo de Piedras Biancas, include a main morainic level at 3400 to 3700 m, and minor moraines at higher elevations up to about 4300. Glaciated valleys, hanging valleys, rock, steps, glacial channels, cirques, arêtes, horns, striae and grooves on polished rock, roche mountonnés, and whaleback forms, are the main evidence of glacial sculpture and erosion. The main morainic level probably represents a Late Wisconsin...
