I live pretty close to this, near Durango CO.
The mined a lot of uranium ore from this area too. Where Lake Knighthorse is now, used to be a uranium mine.

Way back in 1993 I drove up the this dugway without knowing its origin. For me, it was the shortest way from Mexican Hat to Hite.

I have driven that road several times!  I love it!
Beautiful views!
Not dangerous in ordinary bad weather!  I have traveled on it in rain and snow.  Not blizzards or heavy thunder storms, then it might be a bit of a problem, as any road is.

11:39 is the Shafer Trail Road in Canylands National Park.

My understanding was Isabel construction company did the work. That was why it was called Isabel hill.

My Wife and I drove up the Dugsay in 2024. We got about half way up on a clear day, then the winds hit our SUV with such force, they were jerking our vehicle side to side on the road.

We decided to turn back and head back down for safety concerns.

We still have a rain check to return sometime and make it to the top. 👌

Drove this road back in 2010 en-route to Natural Bridges National Park.  It was well maintained; and long as your took it easy and avoided anything stupid (like speedy, sliding turns in a pickup commercial), it was fine.  No place for a motor home or trailer, however!

I wonder what protects the rest of the Navajo Nation from radiation that live in that area and in northeastern Arizona

The movie "Chill Factor" (1999), starring Cuba Gooding, Jr. filmed with an ice cream truck to keep cool a device below 50 degrees (F).
