Thanks for pointing me in the right direction Gordon! I looked up Jack Pine in "Up North" by Doug Bennet & Tim Tiner...the description of the pine cones is pretty accurate to my photo.

This looks like jack pine (Pinus banksiana). Looks like 2 needles per clump and the cones look right as well. See http://en.wikipedia.org/wiki/Jack_Pine and see what you think.
