Flash flood warning in Fourmile Canyon:#boulderflood VIDEO OEM Updates
Jul 8th
It was continuing to rain. The slides get larger as you continue past mile marker 8. Even in our 4 wheel drive TV production SUV we could only make it to the second slide. The command center gave us an escort from Four Mile Fire department. We had to have a radio person with us in case it slid again and we got caught up in a slide.
Initially, a Boulder County Sheriff deputy came up on the slides during the down pour at around 6:00pm. He told us it was all he could do to drive out in his Sheriffs big SUV Chevy.
Four Mile fire chief said that a large amount of the slide had hung up about 50 feet up the hill on a rock out cropping. There was some concern that it would slide again on into the night as the rains continued.
Four Mile Fire was on the scene and stationed through out the canyon to watch for more slides. A large road grader was pushing dirt and a front end loader and 10 Wheel dump truck were working the larger slides.
The hope is to get the road opened by morning. The concern is that it will keep raining and cause major slides.
