The explorer, Fremont, says that on the 13th day of November, 1843, two
of the great snow cones (Mounts Tacoma and St. Helens) were in action. "On
the 23rd of November St. Helens scattered its ashes like a light fall of snow
over the dalles of the Columbia fifty miles away," and it was still burning
on February 16,1844, when another witness described it thus-, "The mountain
burned most magnificently. Dense masses of smoke rose up in immense columns and
wreathed the whole crest of the peak in sombre and massive clouds, and in the
evening its fires lit up the flaky mountain side with a flood of soft, yet
brilliant radiance."
