   • 1988, Robert Phillip Sharp, Living Ice: Understanding Glaciers and Glaciation‎, page 149:

     Another unusual ice-contact feature is an esker, a long, narrow, steep-sided ridge of glaciofluvial sand and gravel inhabiting a glaciated area. Eskers tend to follow valleys and lowlands, carefully picking a course between obstacles.

   • 1999, L. Clayton, J. W. Attig, D. M. Mickelson, “Tunnel channels formed in Wisconsin during the last glaciation”, in David M. Mickelson, John W. Attig, editors, Glacial Processes, Past and Present, page 77:

     Another objection to the tunnel-valley interpretation comes from a comparison with eskers. […] The esker rivers and the tunnel-channel rivers of Wisconsin therefore seem to have been the result of significantly different meltwater regimes.

   • 2001, Allan D. Randall, Hydrogeologic Framework of Stratified-drift Aquifers in the Glaciated Northeastern United States, US Geological Survey Paper 1415-B, page B37,

     The multiple deltas must have formed sequentially, which led Thompson (1982) to conclude that the eskers were built in successive segments.
