I seen you had said that the creek went through the park until the 1970s when it was reconstructed to make room for Mesaba Avenue. I don't believe that is entirely correct. I lived on First Avenue West and Fifth Street in the 1960s, and it was already covered at that time. Matter of fact, in 1968 the park flooded so bad it took out the steps and almost all of First Avenue at the entrance of the park. I am not sure when the creek was covered, but I think it was in the 1940s. However, you did something I would have never tried. That trek looked pretty spooky. Thanks for the video!
