In this module we examined Mt. St. Helens. We looked at the volcanic event itself andthe geologic effects of the eruption.

In the reading assignment we discussed the First and Second Law of Thermodynamics.

At the Web site we examined:
Background Information including

	1.	Paleoplains
	2.	Underfit Streams Examples of dry channels associated with underfit streams which once carried surges of flood waters: a. Mississippi River in eastern Missouri b. central Sahara south of Tibisti c. Wright Dry Valley, Antarctica d. scabland of eastern Washington State
	3.	Upright Deposited Logs

The volcanic event itself

	1.	Earthquakes
	2.	Landslides that displaced the water in Spirit Lake and blocked Toutle River
	3.	Steam blasts of volcanic ash and steam
	4.	Violent eruptions
	5.	Mud flows
	6.	1,000,000 logs covering Spirit Lake with floating mats

The geologic effects of the eruption

	1.	The rapid deposition of strata with minute layering The greatest thickness of deposit was 600 ft. (called Langes Crest)
	2.	Canyon erosion through solid rock up to 100 feet deep
	3.	Canyons formed by steam pit collapse
	4.	New channels cut as landslides blocking Toutle River are unblocked a. 5 canyons, some over 100 ft. deep were cut b. A "miniature Grand Canyon" was cut in one day

How the events at Mt. St. Helens can be applied to other geologic formations

	1.	Grand Canyon
	2.	Santa Cruz River (Condor Cliffs)
	3.	Fossil forests (such as Yellowstone)
	4.	Formation of coal
	5.	Geologic column (the relationship of Noah's Flood to the geologic column)

Under Current Research we examined cavitation
We saw the magnitude and short time frame of cavitational reduction. These findings aid the recent creation model by reducing the time frame needed to change massive amounts of pre-flood earth crust into what has become our present sedimentary layers.
