PORTER, Ind. (AP) — A national parks advocacy group says the boundaries of the Indiana Dunes National Lakeshore in northwestern Indiana are confusing.

The Times of Munster reports (http://bit.ly/u7qYdW) the National Parks Conservation Association is calling for a study of the park boundaries.

The report calls for a boundary study performed by the National Park Service at the request of Congress to identify how to fill gaps and connect the park that is fragmented into 16 disconnected pieces.

The conservation association says it also is concerned about inadvertent encroachment on the park by neighbors.

Indiana Dunes National Lakeshore Superintendent Costa Dillon agrees the park's boundaries can cause difficulties and lost opportunities. But he says the National Park Service is not looking to do a boundary study now.
