wonder how long it would take to make it through the 700 feet?

Probley the rest of your life !!!

It doesn't look real to me. The white water in the first pic looks photo shopped.

I have not seen this one its self , but I have seen 3-4 others



No snide ass comments about glorys holes JIM

No 'shop skills -this is my first ever creation apart from a few 'thread bombs" (and I needed rescuing/therapy/beer several times during creation), but never one to resist a challenge......

Well done Monster!!!!

ta :o

I actually stood and looked at that exact drain with my girlfriend during college days. It's just up the road from UC Davis. It made the hair go up on the back of my neck. It is quite a horrific sight when you think about it. Then you just walk down the road a hundred feet and look way down in the canyon at that jet coming out. I was amazed and appalled by the one little swimming pool lap lane divider that surround the hole out about fifty feet. I wonder how many ducks and geese have not noticed it in time. The only advantage over the usual bottom of the dam (safer version) is that this thing auto regulates. Water level drops - draining stops.

That road is fun though. There are about 10 creeks that cross it at concrete flats. They were fun to hit at about 45MPH. 3" deep by 10 feet wide. Nice and straight. BOOOOSH!

Absolutely! Here's one, that one might perhaps actually use for that purpose.

Fortunately for life, as we know it, on Earth, water has the amazing property of cohesion which allows it to be a liquid.
As the water flows over the rim, it's all cohesively connected and uniform, then gravity causes it to increase speed. When the water accelerates it gets torn away from the slower water behind and the faster water ahead. Droplets form of the water that's close enough in speed to have cohesion triumph. That's the white in the first picture, water droplets which scatter light.:cool:

Monster, that's awesome! Exactly what I was seeing in my head.

Go, you!

I didn't think you were supposed to go in the out hole.

I guess the spillway shaft itself is just a tunnel drilled through solid rock? I'd like to the see profile of that...I mean, it has 770' of drop, and has to make a bend from vertical to horizontal at some point. The water pressure at that bend must be tres' impressivo.

That's a myth perpetrated upon clueless men by unadventurous women... :redface:

Two views of a dry glory hole.

see Jim, I told ya that giant sucking sound was coming from California
