CHESTERTON, Ind. (AP) _ The names of four crew members who died when a sand barge sank off the shore of the present-day Indiana Dunes State Park have been read at the dedication of the shipwreck site as Indiana's first underwater preserve.

The 100-acre J.D. Marshall Preserve was dedicated Monday in Lake Michigan near the city of Chesterton, about 15 miles east of Gary.  The sand barge sank on June 11, 1911, when it sprang a leak and capsized in a storm.

The Times reports the site is open for diving and fishing but precautions will be in place to try to prevent treasure-hunters from removing items from the wreckage and to keep boat anchors from damaging it.
 
The Indiana Natural Resources Commission approved the preserve Sept. 17.
