During winter, the outwash plain lacks water. But during the summer melt season it is filled with channels. Then, from 0:16 to 0:23, Batman walks over a ridge. Note that the ridge is between the outwash plain and the glacier. What is the best scientific term for this ridge?

Terminal or End Moraine

Explanation:

The best answer here is end moraine.

End Moraine is also known as Terminal Moraine.

In the terminal moraine, the glacier once existed at this ridge, and boulders, cobbles and fine material were dumped at this spot – much like your bags are dumped by a conveyor belt at baggage claim at an airport.

Other types of moraine is the lateral moraine.

Thhe lateral moraine consists of till forming a ridge on the side of the glacier. This is not on the side. Trimlines and glacial are the erosional features and this is a glacial deposit composed of boulders and rocks of different sizes.
