White River Glacier, Alpine glacier on Mount Hood, Oregon, United States

White River Glacier is an alpine glacier on Mount Hood's southern slopes that stretches across multiple elevations. Its surface features deep crevasses and blue ice formations that change appearance with the seasons.

White River Glacier is a remnant of the massive glaciers of the last ice age, which carved White River Canyon. Its terminus retreated 510 metres and its area shrank by 61% between 1907 and 2004. Jökulhlaups from the glacier washed out the Oregon Route 35 bridge in 1926, 1931, 1946, 1949, 1959 and 1968.

The glacier feeds the White River, whose canyon separates Mount Hood's two largest ski areas, Timberline and Mount Hood Meadows. Skiers at Timberline can see the glacier and canyon from many runs, and its lower reaches draw Nordic skiers.

The best time to explore is late summer when access routes become easier to navigate. Visitors should bring sturdy footwear, weather protection, and good directional awareness, as the terrain can be steep and unpredictable.

The glacier's outburst floods, called jökulhlaups, washed out the Highway 35 bridge in 1926, 1931, 1946, 1949, 1959 and 1968. The floods may be linked to rising temperatures and the fumarole field at Crater Rock, at the glacier's head.
