Palmer Glacier is an extinct glacier on the south slopes of Mount Hood in the U.S. state of Oregon. With glacial ice movement having stopped in the mid 1980s, it is now considered a snowfield rather than an active glacier. The former glacier, now snowfield, is situated at an elevation range of 9,300 to 6,200 feet, and was named for Joel Palmer, an Oregon pioneer. Palmer Glacier is the most well-known of the twelve glaciers on the mountain, despite no longer technically qualifying as a glacier, and is a popular destination for snowsports enthusiasts as it is the only US resort that consistently runs it's chairlifts from winter through summer.

The Salmon River is a 33.5-mile (53.9 km) river in the Cascade Range in the U.S. state of Oregon that drains part of southwestern Mount Hood. The entire length of the river is a protected National Wild and Scenic River. Several portions are in protected wilderness. It is affluent to the Sandy River, a tributary of the Columbia River.
