Yup.Fed by the Harding Ice Field. My wife and daughters swim in it at least once every trip. Have a 75 year old man on the island, that dives in from his dock and swims back to shore. Too cold for me.
They have a house in town with a package boiler and hot water heat on natural gas. They also have a wood stove. A huge majority of dwellings in town are heated this way. The garages are also heated.BTW, what does your SIL use for heat and electric during the dark months?
Every sleeping space has a window big enough to escape out of. That is also the reason we have doors on both floors.We did one almost like it in the western UP. Your going to roast upstairs in the loft like being in the sauna if you sleep up there & have a woodstove. Make sure where people sleep they have a window everyone can get thru in case of a fire as we had a fire & lost the whole thing.
That is really nice!Kudos to the OP, not much more satisfying than building you own cabin This one took me, my wife, son and 4 friends 4 years to build. Just one recommendation for anyone considering building: Build the outhouse first!
