Mount Hood, standing out above the surrounding peaks of the Cascade Range in the lower right quadrant of this orthorectified image, is a stratovolcano in the Cascade Volcanic Arc of northern Oregon. It is located about 50 miles (80 km) east-southeast of Portland, on the border between Clackamas and Hood River counties.

The exact height assigned to Mount Hood’s snow-covered peak has varied over its history. Modern sources point to different heights: 11,249 feet (3,429 m) based on the 1991 U.S. National Geodetic Survey and 11,240 feet (3,426 m) based on a 1993 scientific expedition. Regardless, it is the highest mountain in Oregon and the fourth-highest in the Cascade Range.

Visible to the north of the volcano is Lake Bonneville, a reservoir on the Columbia River shared by the U.S. states of Oregon (south) and Washington (north). It was created in 1937 with the construction of Bonneville Dam. The reservoir stretches between it and the Dalles Dam, upstream. It lies in parts of three counties in Oregon (Multnomah, Hood River, Wasco) and two in Washington (Skamania, Klickitat).
