Remembering Mount St. Helens 35 Years Later
by Brian Thomas, M.S. *
The volcano’s main 1980 eruption filled in an entire valley with hundreds of feet of sediment. Another smaller eruption event deposited more material on top of that, and then a third deposition occurred in 1982. Later, a catastrophic flood of snowmelt water and muddy debris tore a gash through those fresh deposits, revealing sharp and flat contacts between each earlier deposit. It also showed that fast-flowing currents can lay down multiple layers thinner than a finger width.
Mount St. Helens revealed to the world that both thick and thin layering can happen fast. Millions of years are not needed to form sedimentary rock or stratigraphic layering.
Sedimentary layers hundreds of feet thick formed within hours during the eruption itself, and then hardened into rock soon after the water drained from them. Could other layered sedimentary rocks in Earth’s crust have formed rapidly?

Limestone, in particular, which forms in shallow tropical seas, can be found today in locations such as the tops of the Himalayas. Obviously a LOT of time had to have passed for once soft sea sediments to have first turned to stone then be raised thousands of feet.
Austen didn’t follow the directions for K-AR dating and then pointed at his absurd results as proof the method doesn’t work. It’s kind of like leaving the baking soda out of you biscuits and wondering what went wrong. K-AR dating doesn’t work for time periods less than 100,000 years because of the relatively long half life of the potassium isotope.
The above isn’t technical but it is accurate.
Today, global warming people would say Mt. St. Helens was because of global warming, like the Nepal earthquake.
I majored in geology, but fell short of a degree when personal problems caused me to drop out. Came within one course of completing the geology portion of the degree, and several non-major courses.
I'm a born again Christian
The Himalayas are a good illustration of what happens when two plates collide. The rock at the top of the mountains was once the underwater shelf of the two continents (Indian plate and Asian plate). India crashed into Asia and at the plate margin, the rock was forced up and is still rising by a net six tenths of an inch. So you find fossils at the summit of Mt. Everest. Plate tectonics keeps all the plates moving, rearranging the continents.
Take your kid’s modeling clay and push two pieces together on a table. At the point on contact, the edges of the clay will be forced up where the contact occurs. Similar structural geology can be seen everywhere there are mountains. In road cuts you will see rocks that were formed in flat layers now being “tipped” up in layers now having steep slopes.
Seen more dust during a SoCal forest fire.
It was different back then. Back in 1977, I remember my brother bringing home a "portable video recorder" that he borrowed from the TV station he worked at. Heavy shoulder mounted camera attached by a video cable to an even heavier black and white reel to reel video tape recording deck.
It was over 6” deep in Idaho. Oncoming traffic would blind you for minutes...quite dangerous as you never knew if someone was coming up behind you. I had a fabulous ride on the TransCanada Hwy back to WI.
A generation, at least, before it became a "cool" thing to do. But that was my brother. Always an innovator and always showing people how to love life.
Yeah, they’re called “anomalies” when efforts like the Ocean Drilling Program did their core samples....
They IGNORED the out-of-sequence fossils.

Heavy Metal Clocks, U-Pb and Th-Pb Dating Models: Radioactive Dating, Part 7
by Vernon R. Cupps, Ph.D. *
The heavens declare the glory of God; and the firmament shows His handiwork. Day unto day utters speech, and night unto night reveals knowledge. There is no speech nor language where their voice is not heard. (Psalm 19:1-3)
The heavens do indeed declare the glory of God, but some people choose to believe that the heavens appeared by random chance out of nothing—a stance for which they are “without excuse.” Paul so forcefully points out in Romans 1:18-20 that who God is can be understood “by the things that are made.” These people tend to support their beliefs with various scientific models such as the radioactive dating methods we have been examining in this series. This article will address the uranium-lead (U-Pb) and thorium-lead (Th-Pb) models.

Older sediments can sometimes lie ABOVE newer ones, a result of overturned beds, heavy folding of rock layers, or thrust faulting, where lower beds are thrust/slid over higher ones along a diagonal plane.
I think they figure the earth is about 4.5 billion years old. I’m pretty comfortable with the timeline that the study of geology has laid out - and knowing that new discoveries will no doubt change the various theories. With some flipping things on their heads. (Like plate tectonics did fairly recently.)
What is amazing to me is how EVERYTHING, from the formation of our atmosphere, the position of the sun and moon, how the earth rotates, etc. all fits together to make life on earth. Of course if it didn’t all fit together, we wouldn’t be here. But to say it, (and life) just happened by chance goes against the mathematical probabilities.
Also amazing - getting back to Mt. Saint Helens - is how well things have come back after the devastation. IIRC they said it would be a wasteland for a long time. And of course the “experts” were surprised. Give nature a chance and she’ll recover really well.
i was there...
well, not there, but stationed at whidbey island, about 300 miles away..
it was a sunday, and we all woke up to earthquakes and explosions the likes of which you never can imagine..
dishes rattled out of the cupboards..
we thought we were under attack (the explosions continued for quite a while, and the ground shook non stop)...
we got in our cars and headed for the base (we were living off base at the time)..
we got there to find out the volcano had erupted.. our aircraft were already in the air.. i worked the line division and had a radio that monitored the pilots...
” we are at 20 thousand feet about to be engulfed by ash, climbing to 30 thousand”...
we are at 30 thousand feet about to be engulfed by ash, climbing to 40 thousand”..
we are at 40 thousand feet about to be engulfed by ash, climbing to 50 thousand”...
now imagine an ash cloud a mile by a mile by 40 thousand feet tall....
i got out shortly after that and remember driving from seattle east..
the ash had to be cleared out of the way by snow plows, and was over 12 feet high along the sides of the road..
I am familiar, but in no way as knowledgeable.
The seeming dichotomy in ‘science practices’ & discussion was my point.
Harry was quite the character.
