MARBLEMOUNT, Wash. — 10-year-old Sage Adams was last seen in a kayak on the Skagit River east of Marblemount.

The boy and his father had been kayaking in separate kayaks Tuesday when his father fell out and had to swim to shore.

Skagit County Undersheriff Chad Clark tells the Skagit Valley Herald that two dog teams tracked from the area about half-mile north of the Marblemount bridge where Sage’s kayak was found yesterday (wed) afternoon.

Multiple search and rescue crews are sweeping the area.
