ice jams!

Had to do a double-take today passing over the bridge to campus from Pine Tree Rd.–Cascadilla Creek was backed up with huge ice blocks jammed at the top of the waterfall that flows right under the road. Crazy! And it’s called, get this, an “ice jam”!
Of course, no camera with me. With heavy rain all night and a lot of water melting and running, not sure how long they will last.

“Ice jams occur when warm temperatures and heavy rain cause snow to melt rapidly. Snow melt combined with heavy rains can cause frozen rivers to swell, which breaks the ice layer on top of the river. The ice layer often breaks into large chunks, which float downstream and often pile up near narrow passages other obstructions, such as bridges and dams.” –NESEC

These can do pretty bad things. Witness the Great Ice jam of April 1909!

    Welcome to the Great White North. Whatever you do, don’t go looking for my post on the tax day nor’easter, lest you think that spring will never get here.

    If this ice jam thing is fascinating to you, go down to Stewart Park sometime. I’ll bet with the winds we’ve had, there’s a bunch of ice piled up on the shore. It can be pretty cool.
