Straight-to-sinuous ridge composed of sand/gravel, deposited in a confined glacial meltwater drainage channel.
A type of straight-to-sinuous ridge (Linear ridge types (various origins)).
Winding, steep sided, narrow, sharp- to broad-crested ridges of cross-stratified and massive sand, gravel, and boulders. May be mistaken for other slightly sinuous or Linear ridge types (various origins). In planform, eskers can be sinuous, anastomosing, and/or discontinuous. Isolated, closed depressions (kettles), commonly water filled, may flank or be part of broader esker ridges.
Eskers may occur in isolation or form networks that branch upflow in either subparallel or dendritic patterns (Brennand 2000) with up to fourth-order tributaries (Shilts et al. 1987). Esker systems may be composed of (in increasing order of scale) anastomosing eskers, short sub-parallel esker systems, and long ...
