The skeleton of a girl about fifteen years of age was discovered at this point in 1931 by a highway repair crew. Although the skeleton has not been dated exactly, scientists believe from the site geology that it may be about 10,000 years old, making Minnesota Woman one of America’s oldest human skeletons. Two artifacts, a dagger of elk horn and a conch shell, were discovered with the bones. Archaeologists believe the girl drowned in Glacial Lake Pelican, which adjoined Glacial Lake Agassiz, a huge body of water that covered much of northwestern Minnesota at the end of the last ice age.
