Genetic information (i.e., DNA) collected from individuals, families, and communities can be used in many different ways and it is becoming more of a discussion topic in tribal communities.NA is obtained by collecting biological samples (e. g., blood, hair, cells from a cheek swab, or even from spitting in a cup). Genetic testing has been advertised to tribes as a tool for determining their enrollment (TallBear 2003).
About the Sleeping Bear Dunes. On the northwestern shore of Michiganâs Lower Peninsula, in Leelanau and Benzie Counties, lies the Sleeping Bear Dunes National Lakeshore. The Sleeping Bear is an area unlike any other, over 50,000 acres along Lake Michigan replete with hills and forests of birch, pine, beech and maple. The Lakeshore encompasses numerous small lakes and rivers (perfect for fishing), sugar sand beaches and, of course, the massive coastal sand dunes and bluffs.
Natural history. The park contains the tallest sand dunes in North America, rising to a maximum height of 750 feet (229 m) from the floor of the San Luis Valley on the western base of the Sangre de Cristo Range, covering about 19,000 acres (7,700 ha). Researchers say that the dunes started forming less than 440,000 years ago.
