Flash Flood at Thompson Canyon, Utah

Total Time = 47 seconds (12.9 Mb)
- We could see clouds and lightening farther up the canyon, but it was sunny and clear near the canyon mouth.
- Shown in real time.
- We got out of Dodge before it ended (or grew), so we don’t know how long it lasted.
- Levee built of woody debris as flood first passes by (best seen c. 19 sec).
- After a short bit at least cobble sized rocks were being carried by the flow.
- At 34 seconds, you see standing waves formed in the flow.
- Note hydraulic jumps seen at 40 sec and 42 seconds as flow cuts across road way.
- As flood subsided, we could see deposition of imbricated clasts (photo below).
