This site is within the May 18, 1980, blast zone, about 8.5 miles from the
volcano; to the northeast, the blast swept out to a distance of 13 miles.
A short trail leads from the road to Meta Lake, an interesting path through
downed timber, to a lake that was only moderately disturbed by the blast. Small
trees on the shore and fish in the lake survived because they were under the
snowpack. One blown-down tree near the start of the trail shows tightly
clustered rings for a few years after A.D.1800 (the year when pumice of the
T tephra was erupted from Mount St. Helens).
A car damaged by the blast belonged to a family killed at their
small mine, on the ridge 1 1/2 miles to the west. Thick tephra layers are
exposed along USFS Road 99 from here to the
Windy Ridge parking lot.
