To be successful as a cave hunter, that is a person who searches the countryside for caves, you must combine a variety of skills. In particular, by experience, the mind now tips me off to areas that are likely cave locations. A sound knowledge of sedimentary geology is helpful, understanding a little about physical geography will certainly add to your success, and most importantly, cave geography really tips the scales. In Ontario it helps to understand something about how glaciers influenced the landscape and of course the human interaction on top of that – in particular the tendencies of farmers over the last 150 years and their preference for plugging openings in their fields with coils of wire and other household debris.
Jeff and I went out searching this past weekend and we found a likely cave location on this area of land above a valley. Thus far researchers have visited and dye traced the most obvious spring out to a resurgence in the side of the nearby valley. We followed along and tried to intercept a possible tunnel entrance. It seems to be that in some cases tunnels get bigger deeper in. In this case we found a large soil pipe that had the sound of rushing water flowing beneath its clayish plug.

The above picture is a spot near where we found our promising soil pipes – it is a blind valley where a small stream disappears under ground.
