I'm still EXTREMELY skeptical - I've seen this "undoctored photograph" in several emails claiming it was taken in a variety of location - Alaska, Canada, Maine and this one from Michigan. Also the for some reason the feet and the shadows in the second picture scream photoshop to me but I'm no expert so won't claim it's been altered.

I'm gonna say that it could be a real photograph but I think what really makes this moose look huge is that those trees are all fairly young and that's not a "single lane dirt road for cars" - more likely an ATV width trail. I could be wrong but while he may be freezer full of moose meat I don't think he's any ubermoose.
