The Philadelphia Inquirer reports Richard Minteer of Westampton was in a remote part of Burlington County when he hit an overhanging tree limb around 12:15 p.m. Saturday.
The kayak overturned and Minteer fell into a swift current on the Oswego River. He then became entangled in some underwater tree roots, but was soon freed by his son and some other kayakers.
Minteer was pronounced dead at the scene a short time later.
