Boulder and Manitou Springs were hit hard this monsoon season, as well as many other towns. Manitou Springs is nearby and there is nothing where paved roads used to be, and the numerous videos of cars being washed down the entrance and exit ramps off of hwy 24, looking like fishing bobbers in water, was just amazing.
It will take a while for all those towns to recover.
The flooding in Boulder was from too much rain, while the flooding in Manitou was from the Waldo Canyon burn scar. The water had nowhere else to go but down hill.
