This image shows a walking trail between two large rock formations in the area known as Congress Hall Canyon. These formations are located near the man-made lake called Lake Delton, part of the lower Wisconsin Dells.
There is no description on the back of this card.
Lake Delton drained out completely after a flood which caused a portion of the impoundment close to the Wisconsin River to erode away, destroying homes in it’s path. The lake was re-sealed and allowed to refill.
This card likely dates from the 1940s.
