...Yukon River Breakup Status...



Based on ice running by Galena for most of the day on Saturday, it 

is likely that the in-place ice from the Boneyard to the Nowitna 

River is getting pushed out. The river is open from Ruby down to 

Kaltag with continuing ice and ice stranded in shallow areas. 

In-place ice remains several miles below Kaltag as of Saturday 

evening.
