If you are not from the Southwest of the U.S.

It's important to know that places like Lower Antelope Canyon and others are subject to Flash Flooding. And this can literally happen any time of the year. However, the most likely times would be during the summer monsoon season in especially Arizona, New Mexico, Texas and possibly Utah and Nevada.

If you see storm clouds upland of you (at a higher elevation that drains to where you presently are). You don't want to be in any dry riverbeds like you might find at various beautiful desert places in the southwest.

You don't want to be walking in any dry river bed of any kind if you see any storm clouds within 25 to 50 miles of you.

This is something that will save your life and to be aware of in the deserts especially in the southwest.

if you see a "DRY" riverbed it means a whole lot of water goes down there at some time of the year and you don't want to be washed away in a flood of a monsoon storm or other storm when that hits.

This is just something to be aware of as tourists from other areas of the nation or world who come to visit these often incredibly beautiful desert places in the southwest.

My worst experience with this was driving near Yucca Valley near where Big Bear Mountain range is and San Gorgonio peak is where it is around 11,000 feet in elevation. I was driving on a paved road in a remote part of the desert above Yucca Valley and saw a wall of water coming at me down the road. So, I was driving my brand new 1968 Camaro and I burned rubber spinning the car around so I wouldn't die. I luckily could drive directly opposite from where the wall of water was coming from so I survived this. But, it was one of the scariest moments of my life to have to face this alone in my 1968 Camaro with a wall of water bearing down on me across the desert.

Another experience when I was a child with my father driving in his likely work truck which was a 1960 Chevrolet Truck with a utility body for electrical work as my father was an electrical contractor. We were driving from Pear Blossom and Victorville Towards Yucca Valley across the desert.

The paved road went up and down 25 to 50 feet or more so in the bottom of these were dry? river washes.

A guy in a car went by us at about 90 miles per hour and was having fun driving through the water as fast as possible to see the water splash up. However, he eventually destroyed his car when it hit around 3 to 4 feet of water in one (dry?) river bed along the road.

It had bent the front fenders and hood so it covered up his windshield. His car was destroyed completely and likely was totaled by hitting the water too fast. Don't underestimate what water can do in these kinds of situations or you might lose your vehicle permanently.
