Effects of eruptions and post-eruptive phenomena on caves and pseudokarst of Mount St. Helens

Beginning June 1980 systematic observations and measurements are documenting the effects of the eruption and post-eruptive events on the caves and pseudokarst of Mount St. Helens. Caves of the Cave Basalt Lava Flow were essentially free of physical impacts by the eruptions, but the biota of some was severely impacted by ashfall. Depending on the local physical geography, some of the caves were severely impacted by post-eruption mudflows.

The effects of the eruptions of Mount St. Helens on glaciers, glacier caves, caves and mudflows, etc.

The objectives of this project are to study effects of eruptions on glaciers and glacier pseudokarst and to map glacier caves and glacier margin and other caves on Mount St. Helens. In meeting these objectives we will document and photograph (1) these features; (2) effects of ashfall and mudflows on newly exposed glacier bed and downslope detritus and erosion produced by melting glaciers; (3) effects on crater, dome and caves in crater.

Snowpack Telemetry (SNOTEL)

The SNOTEL system measures snowpack water content – for runoff forecasts, total annual precipitation, and temperature. We have six such sites on and adjacent to Mount St. Helens.
