Nick Zentner, a geology professor at Central Washington University, puts on the Downtown Geology Lecture series at the Hall Holmes Center in Ellensburg, WA. The lecture series covers a plethora of interesting topics on Pacific Northwest geology. He is a passionate geologist and entertaining lecturer, a lot of fun to watch. If only all college professors could make their lectures this enjoyable.
Available on the Utubes https://www.youtube.com/playlist?list=PLwNJg2mCrcQRYmYJzHUv7YxO40JlNbAWe (https://www.youtube.com/playlist?list=PLwNJg2mCrcQRYmYJzHUv7YxO40JlNbAWe)
There are also a number of his lectures available in Utubes that are not a part of his Downtown Geology Lecture series. All of the ones I've watched have been very interesting.

I took geology in college. Absolutely loved it. Professor was quite the character.

I never got into geology. The best I could do was basic algebra. =D

No math involved. If you look at one of his lectures, you'll see that his primary audience is made up of senior citizens such as yourself. =D
Landslides, volcanoes, earthquakes, oh my!

Sounds like a geometric problem.

When I was a young geek, I loved geology... I geeked on seismology, paleontology, all that stuff... Went to college when the real estate market really started to tank, and majored in Geology... Eastern Kentucky University...
Which was mostly about mining. And when it wasn't about mining, it was about mining.
That was dull to me.
Changed majors.
But I still geek hard on earthquakes...

^^^I have read a couple of books about the Colorado school of mines, and they were really interesting.

My uncle was one of the folks who was mapping mammoth cave.
That was cool.
Coal mining was... dull.

My wife and I went to the World Museum of Mining in Butte, MT, which included a tour of an underground gallery. At one part, all the lights and hard hat lamps were turned off, and you go to see what true absolute darkness was. It was very cool. I have done some minor exploration of the various coal, lead and silver mines around here, but most of them have been blocked off or collapsed due to safety reasons.

Would you please stop going off on tangents?
You're so obtuse...

Growing up as a teenager on Squak Mountain outside of Issaquah, WA., we used to go looking for old coal mines in that area. There were a couple of collapsed mine shafts that were visible from trails up the mountain. There was also an abandoned open pit coal mine on the back side of the mountain.
A buddy and I damn near stepped into an open vertical shaft in an old mine we were exploring near MCB Twentynine Palms years ago (my last duty station in the Corps). Our flashlight batteries had failed, but we continued pushing on into the shaft.
I don't know what made us stop near the edge of that vertical shaft. Something must have finally caught our attention.
God was definitely looking after a couple of fools that day.

Enough with the tricky mathematical wordplay.
Geology rocks.

Their "E-Days" (Homecoming celebrations) in April would shake up the area from their fireworks display. All the pyros* in Colorado would take that opportunity to test out their "effects" for free, resulting in the most impressive fireworks display evvvvar. Before it was stopped, they used to set off cases of dynamite just for grins. Years ago Son2 and I attended one of these and sat pretty close to the ground displays. The shock waves were memorable.
Some explosion videos are taken at their test range, e.g.:

Watch your sound level.

Moon rocks, too.

Geology rocks.
Igneous, sedimentary, or metamorphic?

You wanna see dark, try cave diving at night.

Cave diving is a MAJOR "don't even think about it."
And I've been masked and finny since before I was a teenager.
Floyd Collins took quite a while to die, and likely was helped along by the media kerfuffle... Underwater? Done...

Back then I was invincible! 20 year old Sergeant in the USMC, teaching SCUBA. Me & my bud thought nothing of cave diving around an island ~10 miles off the coast of Mexico at midnight.
Get up the next morning, get breakfast ready for the rest of the group & take 'em out for their training dives.
Good times =D

I loved to SCUBA when I was in LE. We had a dive team, but the only time we looked for a body was helping the Coast Guard off Grand Haven in Lake Michigan. The water was so rough we had to return to the station.
Most of our practice was done in clear water inland lakes. We also dove in the Grand River than ran through town. Once in a contest with the State Police dive team, their commander asked our Sergeant what we did if we got in trouble while on a dive. The Sergeant said, "We stand up." The river wasn't very deep in most places.

I've never done technical cave dives, but night diving lava tubes is really cool. There were a couple of caves we would dive at work the Channel Islands that, depending on tides, you would dive a submerged entrance and then come up into an air chamber. I learned after the first time to never take your reg out and mask off and breathe the chamber air, because sea lion *expletive deleted*it stinks to high heaven in an enclosed space. :laugh:

I was in an Uncle Sugar rescue diving class where they allowed civilian LE into some empty slots in the class. They were Sheriff's divers from one of the southern CA counties and they did a lot of body search and recoveries. The one girl I talked to said most of their searches were in crappy water in pretty much zero visibility, so they'd spend their time feeling their way around the search area, and most times would find a body by grabbing it or bumping into it. That would freak me the hell out.

i understand that rapid water "waterfalling" over an obstacle will hold bodies in the swirl below the falls for a very long time. I'm with Ben on finding them "manually."
Ick.
In watching "Sea Hunt" I always cringed when they went into a cave or other tunnel.
I remember the rather graphic descriptions of when they found the Challenger capsule with the bodies in there. Apparently the capsule hit the water at about 200 mph.
Ick.

Have any of you ever heard of "the squeeze"? Before scuba was around, divers had to use those lead boots and brass helmets and chestplates. If anything happened to the airline from the surface, the loss of pressure from the pump would cause the diver's body to be crushed and squeezed up into the helmet. "Strawberry jam" was the result. :O
