Did South Dakota angler find burial mounds on lake bottom?

Stark-Hump-of-Week-COLLAGEWhen South Dakota angler Paul Stark reviewed a custom fishing map he made with Insight Genesis, he discovered on the lake bottom what he believes could be Native American burial mounds.

« We have them by other lakes in this area of South Dakota, » Paul says.

Indeed, ten burial mounds in the Oakwood Lakes area in nearby Brookings, SD, are « typical of numerous such mounds in eastern South Dakota, » according to the text on a state historical marker there. Those mounds, dated about A.D. 300 to A.D. 1400, according to the historical marker, are probably the remnants of late Woodland or Middle Missouri Cultures.

« All of the mounds are strikingly similar about 3-6 feet high and about 100-150 feet in diameter, » the historical marker reads. « The so-called ‘Mound Builders’ made pottery, stone hammers and projectile points which may still be found in the area. … It is believed that the mounds were built by individuals who carried baskets of earth on their heads and then dumped the dirt to form mounds.”

Shown at one-foot contours at the bottom of a 424-acre lake near Madison, SD, the humps Stark discovered have such steep sides that they appear « almost 3D » on his Insight Genesis map, he says.  « Now that is detail on the humps! Man, I love mapping lakes and seeing stuff like this! »

Paul’s screenshot of these unique lake-bottom structures is this week’s Insight Genesis Hump Day « Hump of the Week. » Have you used Insight Genesis to locate bottom structure not shown previously on any other lake map?
