The Volcanoes of Charles Wilkes

 
 

The Wilkes Expedition - 1838 to 1842

In 1836, Congress approved the sum of $300,000 for a purely scientific exploratory expedition. The expedition, headed by Charles Wilkes, left in 1838 and returned in 1842. The scientific expedition visited at least cursorily most every non-civilised coastal area in the world, including the Pacific Northwest in 1841. Other areas visited include South America, New Zealand, Hawaii, the East Indies, Australia, and South Pacific islands too numerous to list. This expedition also provided the first proof of the existence of the continent of Antarctica. A large number of Puget Sound names which are still in use today were provided by Wilkes' expedition, Commencement Bay (where he started his charting of the sound) and Elliott Bay among them.

Mount St. Helens - 1841

Mount St. Helens was recognized as a volcano at least as early as 1835; the first geologist apparently viewed the volcano 6 years later. James Dwight Dana of Yale University, while sailing with the Charles Wilkes U.S. Exploring Expedition, saw the peak (then quiescent) from off the mouth of the Columbia River in 1841. Another member of the expedition later described "cellular basaltic lavas" at the mountain's base.
