Mount St. Helens, Washington
Excerpt found in Yamaguchi, D.K., Pringle, P.T., and Lawrence, D.B., 1995, Field Sketches of Late-1840s Eruptions of Mount St. Helens, Washington: IN: Washington Geology, vol.23, no.2, June 1995, p.3-8. Yamaguchi, et.al., wrote: "On two occasions in September 1845, British spy Henry Warre saw and sketched watercolors of eruption columns forming over the north flank of Mount St. Helens, Washington. ... Figure 2 [in Washington Geology, June 1995] is the first of two similar sketches Warre made from Mount Coffin. The Public Archives of Canada have assigned a date of September 13, 1845, to the second, more finished sketch, based on Warre's journal entries. ... Within a few days of his original sketches, Warre made a third sketch from Cowlitz Farm a trading post along the Cowlitz River. While Warre made no journal entries for this sketch, it was probably done between September 17 and September 20, 1845, based on his earlier and later notes." |
