It is among the best known of the twelve glaciers on the mountain, and the lower reaches are a popular destination for Nordic skiing enthusiasts.

The upper glacier forms at the base of Steel Cliff to the east of an area known as Triangle Moraine.

The western edge of the canyon is extremely steep and in times of low visibility causes descending mountain climbers on the South Route (through Palmer Glacier to Timberline Lodge) to veer excessively to the west to avoid the possibility of entering the canyon.

This has resulted in numerous search and rescue operations near or in Zigzag Canyon, west of Palmer Glacier.
