Ice In Data
 

Does a historical record of ice in exist? If so, can someone please post it? Thanks.

NH DES tracks it though it looks like you'd have to check year by year. Here’s the link for last year’s data.

Winni is not listed, if I recall correctly, because it never fully iced in.

Ice in was never a big thing in the old days like ice out is.

Not of so much interest in new days either. Too often, the Mount's ports have ice but the broads have some open areas, or they close in and re-open a few days later. Emerson called ice-in last year, but I've never heard much consensus about what that really means.

It is when he flies over and sees no open water.
Its only purpose is for the various pools to have a standard format.

It isn't like the Mount is planning to make the rounds up until that point (really couldn't with ice in some ports) or that it will immediately make the rounds after Ice-Out.

Loons and Ice-in
 

Late or no ice-in is becoming a thing for the loons. Last year, perhaps for the first time, some of Winni's loons spent the winter here, rather than migrating to the ocean. This change in behavior causes trouble, because they lose their flying feathers for about 6 weeks in the winter. If a loon decides not to migrate and the ice eventually closes in, they can be stuck without the ability to fly out and can die. The Loon Preservation Committee (LPC) has been rescuing more and more loons each year. Darwinism, with a bit of human intervention, in action.
