Morainal

Below the glaciers throughout the entire Wind River Range great numbers of morainal lakes are found.

Grand Lake, probably the largest, is about three miles long by one mile wide. Its basin appears to be largely due to a morainal dam.

The ice stopped at Perth Amboy, Metuchen, North Plainfield, Madison, Morristown—leaving a sinuous, morainal, lobate line that not only connects these New Jersey towns but keeps on going to the Rocky Mountains.
