Left Door Cave
Left Door Cave is located in Southern Ontario in the vicinity of Lake Erie. You can stand bent over in the entrance, but the cave quickly tapers down to a slither type passage. Around 30 feet in from the cliff face it appears to intersect a joint. The joint runs parallel to the entrance in the cliff face. With a bit of pushing the cave might open up.
