A moraine is any glacially formed accumulation of unconsolidated glacial debris ( regolith and rock) that occurs in both. Diagram: glacial mass balance Diagram: terminal & recessional moraine Greenbush Kettle, Kettle Moraine State Forest, Wisconsin.

Terminal and recessional moraines mark the farthest reaches of a glacier—its terminus—at a given point in time.Other articles where Recessional moraine is discussed: moraine: A recessional moraine consists of a secondary terminal moraine deposited during a temporary glacial standstill. Such deposits reveal the history of glacial retreats along the valley; in some instances 10 or more recessional moraines are present in a given valley, and the ages of growing trees.
recessional moraine occurs when the retreating ice is paused rather than the furthest extent of the ice.

A recessional moraine consists of a secondary terminal moraine deposited during a temporary glacial standstill. Such deposits reveal the history of glacial retreats along the valley; in some instances 10 or more recessional moraines are present in a given valley, and the ages of growing trees. Other articles where Terminal moraine is discussed: moraine: A terminal, or end, moraine consists of a ridgelike accumulation of glacial debris pushed forward by the leading glacial snout and dumped at the outermost edge of any given ice advance.
It curves convexly down the valley and may extend up the sides as lateral moraines.. Recessional moraines form when glaciers are temporarily stationary during periods of overall glacial retreat and thus are located at higher elevations than the terminal moraine. After glaciers retreat, these end moraines may be greatly modified or destroyed by subsequent fluvial erosion.Glacial Deposition: Glacial MoraineMoraine – Wikipedia
