In 1804, a group of descendants of Carver petitioned the U.S. Congress for ownership rights to a large tract of land in Wisconsin and Minnesota, claiming that the deed supposedly dated at the "Great Cave, May the 1st, 1767" entitled Carver and his family to over of land. Specifically they identified; "the whole of a certain tract or territory of land, bounded as follows, viz.: from the Falls of St. Anthony, running on the east bank of the Mississippi, nearly southeast, as far as Lake Pepin, where the Chippewa joins the Mississippi, and from thence eastward, five days travel, accounting twenty English miles per day, and from thence again to the Falls of St. Anthony, on a direct straight line." This triangular tract in northwestern Wisconsin and eastern Minnesota would have been bounded by lines running from modern Minneapolis southeast to Pepin, then due east to near Stevens Point, and from there northwest roughly through Eau Claire to Minneapolis.
