About a week ago I posted a few pictures of a section the lower Flathead River as it began to freeze over. Yesterday I visited again after 10 days of sub-zero nights. There is an open channel through part of it, but in other places it is covered bank-to-bank with ice. The last few photos are closer looks at the ice cakes as they start to pile up. As the usual cycle of freezing and thawing proceeds, more ice will break loose from frozen areas upstream and add to the stacks of ice cakes in this location.
This time of the year ice builds up along many of the western Montana rivers. So far this year it is less than in many years. Following are a few photos of ice along the Flathead River a few miles from where it enters the Clark Fork of the Columbia, about 110 miles south-southwest of Glacier National Park. In more severe years, the ice in this place covers the entire river and piles up on itself.
