The second-highest mountain in Washington State is, of course, another volcano: Mount Adams!
Known as the ‘brother’ to the more famous (and active) Mount St. Helens, Mount Adams soars upwards to 12,821 feet (3,743 meters). Mount Adams is shorter than Mount Rainier, but actually contains more volume than Rainier. Mount Adams’ early eruptive history begins over 900,000 years ago, and it hasn’t erupted for about 1,000 years.
Still considered to be active (the Glogal Volcanism Program defines ‘active volcano’ as a volcano that has erupted within the past 10,000 years. The current risk of Adams erupting is currently small; heck, Adams’ recent history over the past 10,000 year have been relative small.
Adams is often mistaken by airline passengers for Mount Rainier due to its flat-topped appearance. Adams, however, is far more flat-topped than Rainier. Rainier has three peaks surrounding its summit crater; Adams’ summit crater is covered by flat, rounded glaciers.
Mount Adams is more remote than Mount Rainier or Mount St. Helens, allowing one to experience a much quieter wilderness adventure if one is adventurous enough to get out that way!
Next up: Mount Baker and Glacier Peak!
