Limit 2 scheduled programs per school, first registered, first served.

Johnston Ridge Observatory Programs
Program Offered Eruption Talk (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 Identification Activity (50-minutes):  This hands-on activity is designed for groups of 30 students or less.  Size limit is strictly enforced.  Students discover eruptive 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.

 Ape Cave Programs
  Rangers aim to provide a brief introduction to ALL groups to talk about the cave, the rules, and white nose syndrome.  The following additional options are available dependent on group size:

  • for groups of 40 or less, guided tour of the lower cave (1 to 1 1/2 hours)
  • for groups up to 50, an introduction and one educational stop soon after entering the cave, leaving you to explore the rest on your own
  • for groups over 50, introduction only.
