The Dartmouth Outing Club offers sessions on how to roll a kayak, an essential maneuver to know for anyone navigating whitewater rapids.

Senior Video Producer Chris Johnson dipped into Spaulding Pool to capture the action at recent sessions, which are run by student leaders from the Ledyard Canoe Club and also have a lifeguard on hand.

Some kayakers learn the technique quickly, while others require weeks of consistent work to really get the roll down.
