Glazier Features Observed in Wayne County
Ground Moraine (14,000 to 24,000 years old)- Ground Moraines often show up as rolling, strangely shaped land covered in grass or other vegetation. They don't have the sharp ridges of other moraines. A ground moraine is made of sediment that slowly builds up directly underneath a glazier by tiny streams, or as the result of a glazier meeting hills and valleys in the natural landscape. When a glazier melts, the ground moraine underneath is exposed. Ground moraines are the most common type of moraine and can be found on every continent.
End Moraine (14,000 to 24,000 years old)- As the ice receded, it stopped at various points and built up land form features known as end moraines. End Moraines are ridges that vary in height and composition depending on the length of time the …show more content…
An out-wash may attain a thickness of 100 m (328 feet) at the edge of a glacier, although the thickness is usually much less; it may also extend many kilometers in length. For example, out-wash deposits from the Wisconsin Glaciation can be traced to the mouth of the Mississippi River, 1,120 km (700 miles) from the nearest glacial terminus. The sheet of out-wash maybe pitted with full kettles or dissected by post-glacial streams. Out-wash plains are commonly cross-bedded with units of alternating grain size. The ordinarily gentle slope causes the larger material to be dropped nearest to the glacier. The smaller grain sizes are spread over greater distances. Striated pebbles are uncommon because the striations are worn away during a transport. Out-washes are the largest of the fluvial glacial deposits and provide a considerable source of windblown material. When confined within valley walls, the out-wash deposit is known as a valley
