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.
The magnificent sand dunes are, of course, the main attraction at Great Sand Dunes National Park. Scientists believe that the sand that comprises the dunes has been in the San Luis Valley for 35 million years. They are a product of winds blowing predominately in opposite directions. 2  Star dunes: The many arms of star dunes are shaped by winds blowing in all directions. 3  Parabolic dunes: Oblong designs are formed when vegetated sand prevents parts of the dune from migrating.
