Pacific,
Working in the snow is great. I don't understand how anyone can live somewhere it rains 3 weeks out of 4.
Elm is not a very good firewood. It burns pretty cold and it actually warms you more by hand-splitting it than by burning it. It'll do in a pinch, though. When it's been standing dead for a while like John fetched, it can be a good little workout for the saw, too. It's not bad for this time of year when the days get up into the 40's and 50's (F, of course) and you want to keep a bed of coals in the stove but don't really want very much heat from it. That's what I've been doing and I still have about a yard of it left. I misjudged and still have a little more than half a cord each of beech, red oak, shagbark hickory (maybe really a third of a cord), bitternut hickory, and maybe a quarter cord of black locust.
Probably first all-around choice would be red oak, and/or white ash. If you've got time to season it, not much surpasses shagbark hickory, with it's bitternut cousin not too far behind. A lot of people like black locust and osage orange, but the best (in my opinion) are the first four I listed in this paragraph.
When you're cold, if it's wood, it's good.
