Weekend geography/history lesson...
Mount Adams, situated in the eastern Cascade range of Washington,
east of Mount St Helens and north of Mount Hood,
is the second most massive and the third tallest
volcano in the Cascade range.
It's eruptive volume is about 48 cubic miles
and only Mt. Shasta (Northern CA)
is larger in volume in the Cascades.
About 60% of the mountain is in the Mount Adams Wilderness
while the remainder (the East Side)
was returned to the Yakima Indian Reservation.
