Slide 19: Away from the shores but still within the Great Basin can be found other fascinating sites that are the result of the complex ecological and geologic history of the basin.  Seen here are sand dunes collected near Delta, Utah--they are lacustrine (lake) deposits that were blown by the wind into dunes after the retreat of Lake Bonneville.
