The day of the big storm, March 24th 2011, I went to see the waterfall at Castle Rock SP. I had been to the waterfall may times in the past, but never at its peak flow. Flash flood warnings had gone out for the San Lorenzo river. What suprised me the most was all the little waterfalls flowing out of the hill sides. Starting with that little one in the main parking area. Maybe it was foolish, but I enjoyed being there in the woods during that storm.
