Mount Hood, one of Oregon's highest peaks, rises above the Lolo Pass area on its NW side. Hood is a prominent landmark on both sides of the Columbia River. The summit of the glacially eroded volcano contains several lava domes. At least four major eruptive periods have occurred during the past 15,000 years, including in the late 1700s. Minor 19th century eruptions were witnessed from the city of Portland.
