I had to see it for myself. I saw the video of the Susquehanna River ice jam centered around Tunkhannock, and I wanted an up close look. I got some good photos, so I'm starting a day early.
I've seen ice covered rivers before, but they are usually a solid sheet. The current ice jam features chunks from upstream, pushed against each other to form a mass. There wasn't much movement while I was here yesterday morning. I guess that's why they call it a "jam." You do hear a crack once in a while as pressure tries to force the chunks downstream.
This photo was just upstream from the Tunkhannock bridge, looking to the south.
I'm glad I visited when I did. The jam began breaking up a few hours after I left. Thankfully, there was no severe damage.
