Father De Smet testifies that "in the year 1846 Mounts St, Helens and
Baker became volcanoes, the latter immediately preceding the time of writing
had undergone considerable changes on the side where the crater was formed,"
This corresponds in some degree to the story of John Hiaton, although the
dates are not the same. It is also reported that Mount Tacoma showed signs
of activity at this time.
