The Volcanoes of
Lewis and Clark
Mount Rainier, Washington - Summary
 
Mount Rainier from Paradise, 1975


Mount Rainier, Washington:
Mount Rainier, the highest (14,410 feet) and third-most voluminous volcano in the Cascades after Mounts Shasta and Adams, dominates the Seattle-Tacoma area, where more than 1.5 million know it fondly as "The Mountain". The Mountain is, however, the most dangerous volcano in the range, owing to the large population and to the huge area and volume of ice and snow on its flanks that could theoretically melt to generate debris flows during cataclysmic eruptions.


Eruptive History:
Mount Rainier is an active volcano that first erupted about half a million years ago. Because of Rainier's great height and northerly location, glaciers have cut deeply into its lavas, making it appear deceptively older than it actually is. Mount Rainier is known to have erupted as recently as in the 1840s, and large eruptions took place as recently as about 1,000 and 2,300 years ago. Mount Rainier and other similar volcanoes in the Cascade Range, such as Mount Adams and Mount Baker, erupt much less frequently than the more familiar Hawaiian volcanoes, but their eruptions are vastly more destructive. Hot lava and rock debris from Rainier's eruptions have melted snow and glacier ice and triggered debris flows (mudflows) - with a consistency of churning wet concrete - that have swept down all of the river valleys that head on the volcano. Debris flows have also formed by collapse of unstable parts of the volcano without accompanying eruptions. Some debris flows have traveled as far as the present margin of Puget Sound, and much of the lowland to the east of Tacoma and the south of Seattle is formed of pre-historic debris from Mount Rainier


"Mount Tahoma"
Northwest American Indians knew the mountain long before European explorers reached the waters of the Pacific Ocean. For generations, they knew the mountain as "Takhoma", "Tahoma", "Ta-co-bet" and several other names. Many of the names mean "big mountain" or "snowy peak," or "place where the waters begin." Little Tahoma is the name of prominent rock outcrop on the east side of Mount Rainier. American Indians living both east and west of Mount Rainier traveled to the high mountain valleys each summer and fall to gather berries and hunt deer, goats, elk, and bear. They often camped near berry fields at altitudes between 3,000 feet and 5,000 feet. The forests and meadows around Mount Rainier were important summer hunting and gathering sites for the Nisqually, Puyallup, Upper Cowlitz, Muckleshoot, and Yakama people. On May 8, 1792, Captain George Vancouver of the British Royal Navy anchored his ship near today's Port Townsend, Washington. He wrote in his log, "... the round snowy mountain ... after my friend Rear Admiral Peter Rainier, I distinguished by the name of Mount Rainier ..."

  12. 1860 Map, Columbia River, Washington State, and Oregon (section of original). (Click to enlarge). Original Map: Map of Oregon, Washington, and British Columbia, (1860). This map dates between March 2nd, 1861 (when the Dakota Territory was formed) and March 4th, 1863 (when the Idaho Territory was formed from eastern Washington and western Dakota) Nearing retirement from a thirty year long and rather successful career, S. Augustus Mitchell printed this map showcasing Oregon, the Territory of Washington, and British Columbia. Washington became a territory in 1853, arguing that distances to Willamette Valley kept them from obtaining a voice in the Oregon territorial government. As this map shows, when it split from Oregon proper the Washington territory included parts of Wyoming and Montana and all of Idaho. Territorial government for Idaho would not be approved until 1863. When Mitchell retired he left the business for his son to manage. Washington State University Archives #WSU7. -- Washington State University Archives, 2004
