Summary

A part of the Mason Esker. Image from wikipedia, GNU FDL

A Esker is a long, winding ridge of stratified sand and gravel, examples of which occur in glaciated and formerly glaciated regions of Europe and North America. Eskers are frequently several miles in length and, because of their peculiar uniform shape, somewhat resemble railroad embankments.

Reasoning

An esker is an interesting map feature and should be appropriately tagged.

Appearance

Perhaps looking like a double natural=cliff? To be determined.

Alternate tagging

Use proposed tag natural=landform; landform=esker

The tag natural=ridge is widely used for all kinds of ridges, including some eskers.

natural=esker has also been used.

Discussion

In Norway many such eskers (NO:morene) are very wide, and not so clearly visible in the terrain. They can often been observed as a hill stretching from one side of the valley and ending at the river path. Some times only on one side of the river, other with the river passing in some form of ravine in the middle. - I feel that a natural=landform with a list of landform:type=* or maybe just landform=* can do for many such formations. Even lone dominant hills can be tagged this way. Possible landform values: esker, hill, plateau. --Skippern 13:23, 11 March 2010 (UTC)
