Since the esker was deposited in a flowing water regime, I would not expect to find many fine clays there. And I would not expect to find any large boulders, >1m in an esker.
The moraine on the other hand will have parts that have been formed by rocks grinding each other in a comparatively waterless regime. So it will have lots of fine clays. Boulders >>1m could even be a feature of a moraine.
esker is another name for glacial ridge
An esker is formed by the deposition of sand and gravel carried by meltwater streams flowing within or on top of glaciers. As the glacier melts, the sediment is deposited in ridges or sinuous mounds along the path of the flowing water, creating a long, narrow ridge known as an esker.
A ridge left by a glacier is called an esker. Eskers are long, winding ridges of gravel and sand that were deposited by meltwater flowing underneath or within glaciers during the last ice age. They are usually found in areas that were once covered by glaciers.
An esker is a type of hill made up of glacial debris (sort of a moraine). They are generally found in areas that have had continental glaciation (past ice ages) and differ from the moraines seen at the edges of glacier ice sheet in that they are elongated in the direction of ice sheet flow. Esker is from old Irish meaning "ridge". A esker is commonly long and sinuous. see : http://en.wikipedia.org/wiki/Esker
"Eskir"EskerA glacial ridge could be defined as several things:- An arête: a steep ridge formed by glaciers.- Corries: formed through glacier action.- Eskir/esker: a ridge of sand and gravel deposited by glacial movement.- Serac: a block of ice formed by intersecting crevasses on a glacier
You may be referring to an "esker," a snake-like deposit of sediment left by a stream of running water underneath a glacier. At the edge of a glacier, a "moraine" also can form. A moraine is a pile of sediment and debris pushed by the glacier that forms alongside the glacier - a lateral moraine - or at the end of a glacier's run - a terminal moraine.
esker is another name for glacial ridge
The glacial formation of the collection of loosely arranged glacial debris which may include rock and soil that occurs in recently glaciated and previously glaciated parts on Earth is called moraine. It may contain debris ranging in size from sand-sized glacial flour to huge boulders.

An esker is formed by the deposition of sediments carried by meltwater from a retreating glacier. As the glacier melts, the sediment is deposited in a sinuous ridge-like formation. Eskers are typically composed of sand and gravel.

A long winding ridge made from deposits of sand and gravel is called an esker. Eskers are formed by the melting of glaciers and the deposition of sediment as the flowing water carries and deposits material in a sinuous ridge-like form.
