Ocheyedan Mound, Osceola County, Iowa

Among the many interesting surface features of Iowa, there are few, if any, that have attracted more attention or have excited more wonder than Ocheyedan mound, which is thought by many persons to be the most remarkable and beautiful hill in all northwestern Iowa. It lies within a region of varied topographic features, including lakes, ponds and marshes, level prairies with fine farms, and precipitous hills, some of which are in groups with no distinctive arrangement, while others, perhaps best illustrated by Ocheyedan mound, are isolated and rise somewhat abruptly above their level surroundings
