What the hell is quicksand actually?



It's where the percent water content of soil/sand is low enough to suspend the sand particles but high enough to not support the weight of a person. It's actually fairly common here in some of the "dry" desert washes and slot canyons. They'll be a precipitation event where most of the wash dries out, but there will be patches of quicksand where the water doesn't evaporate.

They had some on Gilligan's Island. A tiny uncharted island in the Pacific has it, but nobody can find any in North America.

Right. And when you disturb quicksand it loses its cohesiveness.

While driving piling you are vibrating and shaking whatever strata you are driving in. Quicksand starts to liquefy and the piling may drop a few feet on its own.

Maybe Oilfield is, but there are a bunch of posters here that would be in trouble.

This and amnesia…. Every show on teevee in the late 70s and in the 80s had at least one character who got amnesia at some point…. Then they got knocked in the head and recovered all their memory.

I have never seen taxonomy turned into a verb. Did you just make this up or is this a legitimate use of language?

Watching Tarzan as a kid, I worried about quicksand and man-eating plants. Wasn't ever going to Africa.

Never lost anything in quicksand, but lost some knee boots in the marsh..

Sand that has a high water content, but is viscous enough to trap in the moisture. It's quite solid until something shocks the system, like someoen stepping in it.

Fun fact, it's physically impossible for a human being to be completely submerged in quicksand. Quicksand is around twice as dense as the human body. At most it can make it up to around a human waistline.

Now just what the frick is that supposed to mean? I lifted weights in highschool, so the BMI doesn’t count.

I was doing a survey on a river bank, it was pretty sloppy, I had on knee boots. I was walking along, paying more attention to the transit than where I was going, I took a step into a wet sandy area and sunk in over my boots in a second. My co-worker thought this was hysterical, but I crawled out of my boots onto a solid spot.

The worst part was walking back to the truck barefoot covered in muck. I don't know 100% if that was quicksand, but it sure acted like it.

It meant that I thought you were more intelligent (less dense) than many here...

Hell, maybe I was wrong.

It is just saturated fine grained material. I have been stuck a few times in silt/clay when my local river is down. Lost a boot or two. Pro tip, increase your surface area if you are stuck.

interesting side bar: if you listen to Dan Carlin's Blueprint for Armageddon (WWI history podcast), he goes into detail about soldiers becoming trapped in the saturated "pudding" dirt of Flanders (3rd Ypres/Passchendaele). They would stay trapped there for days crying out for help until they completely sank under. Any movement would cause them to sink lower and their friends couldn't get to them or they would become trapped as well. And then they started to rot.

Same as other mentioned. Got stuck in some quick "mud" as a kid crossing the marshy end of a slew on the Tennessee River.

Went up to my waist before managing to get horizontal and crawl out.. Lost my rubber boots and came out completely covered in muck.
