Cornwall-on-Hudson-Do you have a story of the Hudson River? The Museum of the Hudson Highlands is launching its Nature of the Hudson summer program series on June 5 and 12 with "The View from Kowawese Tells Many Stories: Which Do You Know?" In this program, participants listen to the stories behind Murderer's Creek and Bannerman's Castle, Chevaux-de-frises, the Storm King Decision, and the New York City aqueduct. They are also invited to share stories of their own. The summer series presents educational programs about the history and science of the Hudson River. Each program poses a question n and visitors who can't answer it at the beginning of the program will surely know it by the program's end. All programs take place on Saturdays at 10 a.m. and meet in the parking lot of the Kowawese Unique Area at Plum Point, Route 9W, in New Windsor. All ages are welcome. General admission is $3 for children, $5 for adults and for museum members, and $2 for children and $3 for adults. Upcoming programs include: June 19 and June 26 - Water Quality: Does "dirty" water mean pollution? After a discussion of the river's health, participants will perform water quality tests, pose questions and solve a mystery. July 10 and 17 - Topography: Is the Hudson River a fjord? Participants take a look at the geology behind the topography of today.
