Group photo taken in the crater (by Jeanne Fromm): back seven (L-R):
Erik Donaldson, Nolan Brewer, Shauna Nyborg,
Mike Kalk, Cooper Brossy, Willie Scott (CVO), and Brennan Jordan; middle
five: Emily Owens, Ashley Meganck,
Michelle Heimgartner, Katie Wagner, and Jenn New; front pair: Spruce
Schoenemann and Toby Meierbachtol.
Route taken into the crater of Mt. St. Helens; note that the DEM from
which
this image was developed is based on the late 1980 topography so the
dome is quite small
Northeast ridge of Mt. St. Helens, note drainage development since 1980
eruptions
View of the incised Goat Rocks fan below the mouth of the crater on
the north
Striae caused by the sliding of the debris avalanche over the Goat Rocks
fan
The group takes a break before entering the breach into the crater;
the dome is in the background
The group approaches the dome in the crater of Mt. St. Helens
A glacier has formed between the dome and the crater wall, the dirty
snout looms in the center
of the photo; this is the youngest glacier in North America
and perhaps the only glacier in the lower 48 states that is advancing!
The dome of Mt. St. Helens
Looking north out crater; the white cliffs are deeply weathered rhyolite
cut by basalt dikes
which fed the overlying lavas of the Castle Creek eruptive period ~2000
years ago;
also note Mt. Ranier in the distance
Willie Scott (CVO) leads a discussion of geothermal springs at Mt. St.
Helens
Brennan Jordan gets a feel for the contrast between two streams at their
confluence; the stream on the
right is born of glacial melt water, the stream on the left emerges
from a field of thermal springs and is uncomfortable to the touch!
Peering over the edge of Loowit Falls toward Spirit Lake
A large breadcrust bomb (lens cap for scale) formed by the continued
expansion of the
interior after a rigid crust had formed
Radial polygonal jointing, a small-scale equivalent to columnar jointing;
this jointing indicates that
this block was still hot when in rolled off of the lava dome
On the return trip to Walla Walla we took a side trip to Paradise on
the south slopes of Mt. Ranier;
this photo shows Ranier and Little Tahoma (right) on the drive from
White Pass to Paradise
