Preparing for Breakup Tripod at Galena on the Yukon River Yukon River at Galena on 18 May. They put the tripod up near the pilings a few days ago. When breakup gets closer they will attach a timer to the line coming from the tripod. As soon as the ice moves the timer will trip so we will know the exact time that breakup starts here.
