I would think there would be significantly less sediment build so close to the dam. The area around fort Moqui gets the full sediment load of the Colorado. I don’t think there are any large sources of sediment coming in near there?Wonder how much silt buildup has obscured the traces of that Kane Creek road. Think Moqui fort near Hite or even inside Cathedral in the Desert.
I would agree there’s not a huge amount of deposition of silt that high up along the base of Gunsight, but it wouldn’t take much to obliterate a road. More likely its disappearance is from a little deposition, plus good old fashion erosion from water rising and falling over that area.I would think there would be significantly less sediment build so close to the dam.

Great photos...THX so much. The 1871 Powell pic was amazing, but what really got me were the footprints in the sand...My kids think it’s funny that I collect coins and find them so “cool”, but one of my favorite things from other wordlings are old photos. Thanks for everyone sharing, especially @JFRCalifornia
@Rainbowbridge got me thinking about 2 things: sentinel rock, and ….. Rainbow Bridge. Here’s a few of my favorite shots of sentinel rock:

Looking up into future Wahweap Bay - 1962. I like how this one shows how "small" sentinel is compared to the adjacent canyon walls.

The tippy top of Sentinel before it disappears. Not sure of the date, but maybe mid to late '63 looking at the penstocks at the dam.

Great shots of Sentinel Rock! I’ll add a few more, all of which pre-date the lake. The first is an aerial from April 1962, similar to @SkibumUT's shot from 1958, although a little less clear, but with a wider shot of the river.My kids think it’s funny that I collect coins and find them so “cool”, but one of my favorite things from other wordlings are old photos.

That's to cool, but get the ear muffs outView attachment 26394
Art Greene's tour boat at his Cliff Dwellers Lodge. He ran tours in it from Lees Ferry to Rainbow Bridge before the dam, it was Air Powered by a Pratt and Whitney Wasp Radial engine, maybe 600hp.
(or more) That is likely a Bureau helicopter in the shot out scouting and mapping to build the dam. That's an airstrip just to left too. The name of the boat is in Navajo "Tesh Na-ni-ah-go Atin" (The trail to the rock that goes over) Employees just called it the Na ni for short. Circa 1957.
All these folks especially Art Green and company continue to inspire me. What and amazing period in Arizona and Utah history. Who would build something like this boat? Seems now that they were all larger than life characters.
Too cool, I would like to hear more about how this worked.Brass indeed.

Enough brass to tram a haul truck out over the canyon to the river below.

Fuel was really cheap if you owned the only gas station and FBO for miles around. I suspect the Bureau Bell Helicopter was coming in for lunch and fuel at Cliff Dwellers Lodge there on the highway just above Lee's Ferry. Art did have to stash fuel at their planned stops along the way because that engine likely consumes something like 50/60 GPH. I've seen pictures of Art with Gerry Cans going upstream to stash them up lake aboard a boat with a small outboard. But yeah, passengers had to wear earplugs and write notes to each other because of open exhaust and the prop. I'm sure it was like 150db, insane.That's to cool, but get the ear muffs out
Bet the 600 horses went through some fuel, but it was cheap then.
