Break up, is another term that is used in Alaska. Because of the snow we get and lakes and rivers freeze up when Spring is coming here it take a while. The time that Spring takes to melt all of the snow, thaw the rivers and lakes and ground is called Break Up.
The term Break Up is fitting also because there is a places that set up various methods of telling when the ice breaks and actually goes out. The purpose of doing this is Alaskan fun. People enter date and time for which ever lotto they prefer. Then wait for the fun and see who wins. Here is a link with some information about the process: http://www.time.com/time/magazine/article/0,9171,869038,00.html
All sorts of items show up as the snow melts. And there are clean up days organized to take care of that.
So if you hear of Break Up in Alaska you will know that it is not some new reality show.
