You may remember the valley of Keefer Creek that we drive across when we drive to Owen Sound. I have been under the impression that the tiny streams we see there, that represent the beginnings of Keefer Creek, emerge from springs around the hills south of the highway (to the left below). The rock cuts that we go through at either end of the valley tell me that the entire valley is indeed below the escarpment. However a friend here mentioned to me that the creek actually flows above the escarpment ridge before dropping down into the valley, and there might be sinkholes involved, so we went exploring.
