High-latitude glacier (HLG) deposits and arcuate ridges associated with slopes interpreted as drop moraines on Mars.

Note: Survey was conducted on all large steep slopes at northern high latitudes (from 55N to the edge of the main part of the polar layered deposit; PLD) using THEMIS daytime IR images. Our search in southern hemisphere high latitudes was also extensive but revealed no additional similar features.
