ALBANY, N.Y. (AP) — A new exhibit honoring the creation of the Adirondack and Catskill parks is opening in Albany.

The state Department of Environmental Conservation is unveiling on Tuesday a display of maps, survey equipment, notebooks and photographs that illustrate the origins of the two wilderness parks. The public "Birth of the Blue Line" exhibit will be located at the agency's downtown Albany headquarters.

The exhibit will feature maps drawn by Verplanck Colvin, who spent decades leading Adirondack surveying crews in the 19th century.

New York Environmental Commissioner Basil Seggos will mark the exhibit's opening with a ceremony Tuesday morning.
