Johnston
Ridge Observatory Programs
Eruption
Talks (20-30 minutes):
Join a ranger
to explore the geologic processes that build up and tear
apart volcanoes. Students will discover evidence of three
powerful events from the May 18, 1980 eruption. Your students
will discover the largest landslide in recorded human
history, the lateral blast that blew down 230 square miles
of forestland, and searing flows of pumice that poured
down into the Toutle River. Students will also have
the opportunity to learn about the 1980-1986 and 2004-2008
lava dome building eruptions.
Rock
Indentification Programs (50-minutes): This
hands-on activity is designed for groups of 30 students
or less. Reservations will NOT be accepted for groups
exceeding this size limit. Students discover
erutive stories told by volcanic rocks as they identify
intrusive and extrusive igneous rock samples by color,
texture, or crystal type.
- Teachers must download the pre-visit
instructional sequence and student worksheets
that are required to conduct this activity with the
ranger.
- Teachers must also print off the appropriate
number of student worksheets for your group--worksheets
are not provided by the rangers at Johnston Ridge.
