SCHEMATIC [22K,GIF]:
Dome Growth 1980-83 - Ground Profile
-- Taken from tracings of photographs from
fixed photo station on crater floor, approximately 1 kilometer north
of center of dome. Products of each extrusive episode include talus that
accumulated during that episode. Scale varies owing to perspective
view; true east-west basal diameter of dome in
December 1983 was about 830 meters.

SCHEMATIC [10K,GIF]:
Dome Growth 1980-86 - Yearly Ground Profile
-- Taken from tracings of photographs from
fixed photo station on crater floor, approximately 1 kilometer north
of center of dome. Includes accumulated talus.
Scale varies owing to perspective view. Approximate 1986 east-west
basal diameter of dome was about 860 meters.
