While the exact date and details of that event aren't set, it promises to be a family-friendly celebration with storytelling and musical events focused on the historical landmark.
On Sept. 19, Halfmoon will also have a "Walk the Byway" day, when participants will walk over 26 miles along the Mohawk Towpath Byway.
Even municipalities with a more distant connection to the historic expeditions are getting into the quadricentennial spirit, and the theme of reviving history in general.
In the Town of Ballston, a celebration centered on Ballston Lake will be held July 11, from 10 a.m. to 2 p.m. The events will be based in Good Times Restaurant.
Though the itinerary is still being constructed, organizers hope for plenty of children's activities, a fishing tournament, plenty of historical artifacts and a flotilla of boats on the lake. A replica of the Onrust, the first Dutch ship built in the Americas, may also make an appearance.
"We don't really have any Dutch heritage in the Town of Ballston, so what we're doing is using the quadricentennial to celebrate our past, and also our present," said Ballston Town Historian Rick Reynolds, who added that the Dutch explorers did a great deal to influence how the area is today.
"If it weren't for the Dutch, who really opened up this state to exploration and colonization, none of these countries would have come in the way they did," he said

There are many events big and small already under way that will last all year (or longer), including art installations all along the Hudson, special Albany Aqua Ducks tours and a fishing tournament in the Town of Bethlehem Saturday, May 9.
