Bridge Canyon slid three times this year. The first was the largest and it happened during the natural cycle in January. The slide path is about 2500 vertical feet from top to bottom. When things started to melt out, I found this 2000 gal water tank that got carried 1000 vertical feet from a spring in the canyon that I use for water. (the tank was not being used any longer). Impressive as the tank ended up about 100 yards below the toe of the debris. It acted like the 'mother of all' airbags!
