- Pothole - A circular hole formed in the rocky beds of rivers by the grinding action of stones or gravel whirled round by the water in what was first a natural depression of the rock. Webster 1913
- The earliest ideas on the creation of potholes are that they were associated with "moulins de glacier" (glacier mills) formed where surface streams on glaciers and ice sheets fall into holes in the ice. Water entering these surficial holes was believed to impact on the bedrock beneath creating a large . The "Moulin Hypothesis", first suggested in 1874, continued to be accepted by many authors until the 1950s. However, commencing in the 1930s, other authors have suggested dissatisfaction with the moulin hypothesis, largely on the grounds that it failed to explain how ice could remain stable long enough for the "giant" potholes to form and why many potholes (like those at Rockwood) were present in large numbers.
