A Preliminary Study of Valley Asymmetry in the Ogotoruk Creek Area, Northwestern Alaska

Résumé

Reports on the pattern and origin of asymmetry in this area, investigated in 1959 and 1960 in connection with Project Chariot studies. Observations from field traverses and interpretation of topographic maps and vertical aerial photographs indicate a high preponderance of steeper north-facing valley sides. This development seems best explained by a sequence of processes initiated by a greater morphologic activity on the warmer south-facing slopes. Effects of snowbanks should also be considered.
