Video of flash flood
May 10, 2007
Here is a great video of a flash flood in Thompson Canyon, which is in Utah and very near these outcrops. This particular video was shot by Doug Jerolmack last summer. I found this on Paul Heller’s website, which is a great resource for videos of clastic sedimentation.
Note the debris-rich front of the flow, full of twigs, sticks, and other stuff (pause at 00:19). After some time, the debris-poor part of the flow comes through.
Pause at 00:34 and note the levee of woody debris that has formed on the edge of the flow. This is a defining characteristic of these types of flows and help keep it going by providing additional confinement.
At 00:43-00:47 (end of footage) note the standing wave that has formed.

I was unable to get the video to play. And when I double clicked on the video to see it at the You-Tube web site, I got a message that said
“This is a private video. If you have been sent this video, please make sure you accept the sender’s friend request.”
you can get it here…you can either view it or download it

I just realized that the times I note above are if the video is counting up…if it is counting down, then the times are 00:28, 00:13, and last couple seconds for the standing wave
