If it ain't snowin' there, we ain't goin' there.
Mark Twain said, "There are lies, there are damned lies, and then there are statistics." Somebody else whose name escapes me said, "If you put your head in the oven and your feet in the freezer, on average you'll be comfortable."

The wisdom of these sages is worth remembering when you contemplate venturing onto the ice this winter, and I mean particularly this winter. You might hear how we're close to normal for heating degree days so far, which is true. But the formation of safe ice is a different cat all together.

I'm expecting unsafe ice for several weeks into the future right now, and in some spots it may never be safe this winter. That's because of the temperature and precipitation patterns we've experienced this December. Let's use Concord, NH, as an example, 'cuz the relevant climatic records are handy.

Over the period Dec. 1 through Dec. 21 (yesterday), the lowest temperature was 2 degrees F on the 9th. The highest was 60, on the 15th, and 52 the next day. That's just a week ago. And since then, we've laid a thick blanket of insulation over the water surfaces that happened to have refrozen, slightly, just before this weekend's storm. And this week, NH may have highs in the 40s with a chance of rain that will percolate through the snow. This is not the prescription for making strong, safe ice.

Ask the locals about the safe and not so safe routes. Choose alternative routes when prudent. Think, "What if?", before attempting the crossing and have a plan ready for getting out and getting rewarmed. Bring the ice picks and the rope. In other words, don't let the averages catch up to you this winter.

I'm gonna thump the drum once more and then clam up on this topic.

NH Fish and Game issued a notice today to "Be Safe on the Ice -- N.H. Ice Conditions Unpredictable" that refers to the same concerns I expressed above.

Note also that we had these high temps yesterday (12/28) in the Granite State:

Berlin Airport: 59
Errol: 60
Pinkham Notch: 59
Whitefield: 56
York Pond: 64 (!)

'Nuff said.
 
I was thinking about how safe the ice was on the first day of winter when I snowshoe'd across Lonesome Lake. I was going to stay on the trail and go around the lake but there was a well defined and broken out path in the snow going straight across towards the hut so I figured it was safe. Alan stayed at least 15 yards behind me just in case one of us fell in. That was a very cold day and the several previous days had also been very cold. I don't think I would have crossed it today. It was pretty warm here in central Massachusetts anyway. I always feel better when my feet get back on real ground.
 
REALLY excellent advice. I love skiing over deep snow on a frozen lake, but always wondered. Now, I'll make sure to always ski right next to fresh snowmobile tracks... that are intact. ;)
Weatherman reminds me of a question I have every time I ski on a lake or stream that has snowmobile tracks. Is it possible that because a snowmobile is going so fast that it doesn't spend enough time on any one spot of ice to break it? This may sound silly, but I ask because I've seen footage of contests where snowmobiles go a pretty good distance over open water.
Another possible advantage they have over a skier on thin ice: Maybe despite their greater weight, because of the larger surface area of the track compared to two skinny skis, the pounds/square foot is less.

So how good a safety indicator is a snowmobile track?
