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 the
Palmer Glacier (a popular skiing area north ofTimberline Lodge since the 1930s) and on the northwest by Reid Glacier. It is the source of theZigzag River which has eroded a large, steepcanyon named Zigzag Canyon. Below the glacier, itssnowfield varies significantly seasonally, varying in length by almost two miles (3.2 km).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. [ cite web
