Callaghan’s Rapids Conservation Area features two waterfalls which are about one metre in height which both span the entire width of the Crowe river, which is about forty to sixty metres across. When river flows are low enough, you can walk out and explore the river bed. The upper waterfall is interesting in that it is formed on a wedge-shaped outcrop of limestone which appears to be beveled down to a sharp edge, right at the crest of the falls. The lower falls is similar, but does not exhibit the beveled-edge crest.
