"The nights are almost invariably cool. In the depth of winter 10 below zero is usual with many a dip to 20°, while 30° to 40° below is by no means infrequent. Nevertheless, these temperatures are not harmful, provided a heavy snow fall has fallen previously, and that, fortunately, is more often the case that not." Elsie Reford, "Lilies at Estevan Lodge, Grand Métis, Province of Quebec, Canada", 1939
