Mount Hood, called Wyeast by the Multnomah tribe (Multnomah (tribe)), is a stratovolcano in the Cascade Volcanic Arc (Cascade Volcanoes) of northern Oregon. It was formed by a subduction zone and rests in the Pacific Northwest region of the United States. It is located about 50 miles (80 km) east-southeast of Portland (Portland, Oregon), on the border between Clackamas (Clackamas County, Oregon) and Hood River (Hood River County, Oregon) counties.
The exact height assigned to Mount Hoods snow-covered peak has varied over its history. Modern sources point to three different heights: convert11249ft0 based on the 1991 U.S. National Geodetic Survey convert11240ft0 based on a 1993 scientific expedition and convert11239ft0 of slightly older origin. The peak is home to twelve glaciers. It is the highest mountain in Oregon and the fourth-highest in the Cascade Range. Mount Hood is considered the Oregon volcano most likely to erupt, though based on its history, an explosive eruption is unlikely. Still, the odds of an eruption in the next 30 years are estimated at between 3 and 7 percent, so the USGS characterizes it as "potentially active", but the mountain is informally considered dormant (dormant volcano).
