ZIGZAG GLACIER

Main articles: Mount Hood

The 'Zigzag Glacier' is a glacier located on the upper southwest slopes of Mount Hood in the U.S. state of Oregon.^[1]
It ranges in elevation from 7,200 to 10,200 ft (2,200 to 3,100 m) with fingers in canyons extending to about 6,400 ft (1,953 m), and lies entirely within Mount Hood Wilderness. The upper extent is divided from Reid Glacier by Illumination Rock. The top of the glacier is at the foot of Crater Rock.
The glacier is bounded on the east by a slight rise shared with well-known Palmer Glacier and on the northwest by Reid Glacier. It is the source of the Zigzag River and has eroded a large, steep canyon named Zigzag Canyon. The glacier's lower extent varies significantly seasonally, varying in length by almost two miles (3.2 km), where it might better be referred to as a ''snow field''.
In 1922, a Jökulhlaup originating from Zigzag Glacier as a flow of dark debris came out of a crevasse high on the glacier. It flowed on the surface more than 650 m (2100 ft) before entering another crevasse, and precipitated a minor panic by those who thought Mount Hood was erupting.^[2]
