ELEPHANT MOUND. A prehistoric earthwork in the Upper Mississippi and Lakes region—where effigy earthworks are common. It is near Wyalusing, Grant county, Wisconsin, and received its name from its massive form and a conjectured pro longation of the nose, supposed to be a part of the original mound when first brought to notice in 1872. The immediate situation is a long rectangular depression, the level of which is only a few feet above the Mississippi at high water. The highest point of the mound (4 ft.) was the hip of the effigy, the length was 14o ft., and the width across the body and to the lower end of the hind leg, 72 feet. When surveyed in 1884 no indication of an elephant like proboscis was found, and it has long been believed that the effigy was intended to represent a bear.
