On Sunday, we drove to Cliff Cave Park. This county park is located in South County, along the banks of the Mississippi River. Sunday was a beautiful day, sunny and unusually warn for November. The park was very crowded, with families and youth groups enjoying hiking and cycling the park’s many trails. We walked and I flew the drone. The park’s namesake is now barred to public entrance. Ostensibly to protect endangered bats that roost within it, but also to prevent a repetition of the tragedy that occurred there in the summer of 1993. 1993 was also the year of the great flood. That summer, a youth group entered the cave and a flash flood ensued. Six people were drowned in the cave.
