Yeh, #1 is a lancaster, it's FM221 which crashed there in september 1950, it's listed on the Lancaster society's website, I saw it from the road and asked the guy who was driving if he knew what it was, he thought it was a kingair, but I flew over the next day and released there's no way, but had no idea it would be a Lanc until I got right up to it, here's another picture that shows the top of the nose
Here's an interesting extra bit of info on #2:
As far as I can tell it's a DC-4, the photos don't show well, but that's definatly part of another nacelle where it's broken off, I imagine the rest of it must have been there at some point or that wing would have been in worse shape... Resolute was used alot by the Americans aswell when the Dew line was being built so I imagine there's as much American wreckage out there as Canadian, in looking up these things I found lots about various military planes abandoned all over the north in the 50s and 60s, more work than they were worth then to get them out.
For #3 somebody mentioned what my guess is, a C-82, I didn't know about it before I was trying to figure it out, at first I was thinking Boxcar because it really looks like it have to of had a boom there that's been cut off, and Boxcars were used by the RCAF, but of coarse the engine was wrong, but the C-82 was similar layout with R-2800s, and that looks like it could be an R-2800. The other thing with that it that I found info on a C-82 that had crashed at a weather station near there that's fuselage had been turned into a shed, so at least it's known they were flying out of there.
There's also a F-27 airliner that crashed in the 70s pretty much entirely intact somewhere near Resolute but I never got a chance to find out where it is.
