A USGS scientist is collecting the ash from the bucket, which was taken back to the Cascades Volcano Observatory for analysis. Results help scientists understand more about the eruption that produced the ash and can give insight into what type of eruptions might occur in the future.

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.
