View from the east side of Mount St. Helens dome looking at the uplift of the glacier and south flank of the lava dome.

Step Channel and Loowit Channel merge on the Pumice Plain. Spirit Lake is visible on the upper right. The yellowish-green color on the surface is plant growth.

The dark "muddy" looking area in the right foreground is old erosional debris flows from Step Channel (on right) over the years. The lighter ribbon of grey to the left of the darker area is a lahar from Loowit Channel from early morning of October 6, 2004. The yellowish-green color on the surface is plant growth.
