Indian Tribes of the Upper Missouri / Edited with Notes and Biographical Sketch

Climate

The climate is pure and dry and perhaps the healthiest in the world. In the months of May and June, when east winds prevail, much rain falls, but during the rest of summer and fall the season is generally dry and moderately warm, except a short time in July and August, when intensely hot. There are occasionally severe thunderstorms accompanied by rain or hail; not more, however, than three or four in a summer, and these in a few hours swell the smallest streams so as to overflow their banks, but with the ceasing of the rain they fall as suddenly as they rise, and do no damage, as there are neither crops nor fences to injure. Tornadoes we have never seen here, although they do happen on the Missouri far below this place. Severe gales are occasionally met with, lasting but a few minutes. With regard to temperature and other natural phenomena I refer you to the accompanying tables.
