ALBANY, N.Y. (AP) - When explorer Henry Hudson got as far north as he could go on the waterway that would later bear his name, he didn't stick around long or wander much beyond the riverbank.
''They did not venture far from shore,'' said William ''Chip'' Reynolds, captain of the Half Moon, a full-scale replica of the ship that Hudson, an Englishman, sailed for the Dutch during his 1609 voyage to the New World.
Hudson and his crew spent only four days at what would later become Albany, but others followed his route upriver, mainly Dutch merchants looking to trade for the fur of beavers trapped by local Indian tribes.

Those enterprising Dutchmen established Fort Orange (later renamed Beverwijck, or ''District of the Beaver'') 15 years after Hudson's voyage on ''de Halve Maen.'' The English renamed the settlement Albany when they took control of Holland's New Netherlands colony in 1664, but the Dutch influence here and along the Hudson Valley lasted well into the 18th century, and plenty of remnants can still be found today.
Many communities between Westchester County and Albany are hosting festivals, concerts, exhibits and other events to commemorate the 400th anniversary of Hudson's voyage, along with a belated 200th anniversary celebration of Robert Fulton inaugural steamboat trip up the river in 1807.
Here are some of the signature events, along with listings for museums and historic sites hosting related exhibits.
