The Alpine Club of Canada's annual camp at nearby Vermilion Pass in 1912. Following the camp, this account was written as to the naming of the lake, "Boom Lake is so called from the fact that near its eastern extremity an old moraine, at one time the bounding wall of the lake, now just touches the surface which has overflowed it. It spans the lake in a crescent, some distance from the eastern end, and intercepts the driftwood floating down the lake. The appearance created is that of a lumber boom, and hence the name." The logs are provided by avalanches that come down from the slopes of Boom Mountain at the eastern end of the lake.
