Abstract: Obvious indicators of past ice breakup levels are the ice scars left in the bark of trees by ice abrasion. These have been used previously to determine ice levels. However, a question that has always been associated with this use is whether the ice scars do indeed provide an indication of the highest breakup water levels each year. In 1979 an ice jam occurred on the Smoky River in Alberta, and the water levels caused by this jam were documented by the Alberta Research Council while the jam was in place. In the following summer, the ice scars left by this ice jam were documented. This paper presents and compares the results of these two sets of measurements. It is concluded that ice scars do indeed provide a reliable indication of the maximum breakup water levels.
