How many states in the United States of America have sand dunes?

The states: Arizona, California, Colorado, Idaho, Kansas, Michigan, Nevada, New Mexico, Oklahoma, Oregon, Texas, Utah Washington, and Wyoming... Nebraska is listed as a lost dune site...

It's Indiana, not Michigan

Thanks FightingGiant2078 for the information that should have been given in the answer. Without the information you provided, I would not have known the states that had dunes.

the information in the answer is not only incorrect but missing some of the states that have sand dunes.

FightingGiant2078, Thanks for this information.

mwstevens, apparently you have to redo the info on this question

So does Massachusetts on Cape Cod.

Indiana has dunes too.
