...HEAVY RAIN EXPECTED FRIDAY NIGHT AND SATURDAY...
THE HEAVIEST RAINS OF THE SEASON SO FAR ARE EXPECTED OVER THE AREA
EARLY THIS WEEKEND. THE BULK OF THE RAIN WILL FALL FROM FRIDAY
AFTERNOON THROUGH SATURDAY AS A STALLED COLD FRONT TAPS INTO
TROPICAL AIR. RAINFALL ACCUMULATIONS ARE EXPECTED TO BE GENERALLY 2
TO 4 INCHES IN THE MOUNTAINS...WITH OVER AN INCH POSSIBLE AT LOWER
ELEVATIONS.
A cargo cult is a type of religious practice that may appear in traditional tribal societies in the wake of interaction with technologically advanced, non-native cultures. The cults are focused on obtaining the material wealth of the advanced culture through magical thinking, religious rituals and practices, believing that the wealth was intended for them by their deities and ancestors.
Field Trip #420: From Disaster to Recovery: The Hydrogeomorphic, Ecologic, and Biologic Responses to the 1980 Eruption of Mount St. Helens (cost: $75)
Leader: John Major
[abridged] Description: ...Within minutes to hours on May 18, 1980, hundreds of square kilometers of landscape were devastated by a massive debris avalanche, a directed volcanic blast, debris flows, pyroclastic flows, and extensive tephra fall...
...This field trip travels along the Toutle River valley examining the impacts of, and the hydrogeomorphic, biologic, and ecologic responses to, the 1980 eruption. We will visit engineering works designed to control downstream sediment movement, Johnston Ridge (8 km from the volcano’s crater) which bore the brunt of the directed blast, and hike a 4-km-long trail loop on the massive debris avalanche deposit.
Field Trip #425: The Dynamic Landscape on the North Flank of Mount St. Helens (cost: $95)
Leader: Steven A. Austin
[abridged] Description: This six-hour hike follows a 13-kilometer-round-trip route to an extraordinary geologic location called “Breached Dam Overlook” just seven kilometers north of the crater of Mount St. Helens. The trail goes from the Johnston Ridge Observatory onto the largest landslide deposit to have accumulated during human history...
...The objectives of the trip are (1) to identify, classify and name individual landforms within the upper North Fork Toutle River landscape, (2) to relate the landforms to the sequence of events and processes that have occurred next to the volcano, and (3) to ponder questions about how the landscape at a volcano changes through time. Landforms on the debris avalanche landscape are relicts that have been impacted significantly by geomorphic processes that exceed a certain minimum energy threshold. Following the debris avalanche of May 18, 1980, the most significant event was the mudflow of March 19, 1982. That mudflow event breached the natural debris dam, caused adjustment within the drainage basin, and derived the present landscape. Now that the power of geomorphic processes has diminished, finer sediment is what is being moved. Channels are incised and armored with coarser clasts, and valleys are now plugging with sediment. Johnston Ridge Observatory on the west side of Mount St. Helens Volcano National Monument is the staging area this roundtrip hike.
