The phenomenon of ice-push ridges on lake shores is a fairly common one, and the enormous pressures developed by ice need no comment. All of the lakes in the Okoboji region show ice-push ridges along their shores, with effects that persist for several years. Shimek (1915, Pl. VI, Fig. 3) included an excellent picture of such a ridge in his Plant Geography of the Lake Okoboji Region.
