Cool! I think I'm gonna just pick this DVD up...reminds me a lot of Piranha by Joe Dante, which was a favorite of mine as a kid as well. I missed Grizzly though. :?
Actually there are tons of trees at the Outpost site, it is located on a cleared plateau just past Salmon Glacier. There is actually forested mountainside the whole way up and to the east of the camp is complete forest! Carpenter, Cohen, and Cundey shot and edited very cleverly, concealing the trees right behind the camp. Once you get up there and see how it actually lays it becomes clear, but here is a very good pic that SPC made up showing how the Outpost buildings sat on the site.

This is an awesome photo taken from the main mining road, looking almost west north-west. There are no shots of the camp in this direction in the film. This pic also clearly shows how this plateau was back-filled and leveled to contruct the set, and the two access paths up onto the site. Remains of the camp lay scattered all about the gravel area and the Norwegian chopper remains lie where it says 'Building Area'.
I don't think bears will be an issue, but again, there is no doubt that there are LOTS of bears in this area. We
will see them. Any food can be tied up in trees. I'd like to see too if we could drive right down onto the site, there is a road (read: gravel trail) coming down from the main road on the left of this photo but it is a very steep incline and dropped off about a hundred feet on one side and both SPC and I agreed not risking it and we all hiked down. (And that meant hand bombed the 15' rotor up and out.) There are sudden,
huge drop-offs right behind Mac's Shack and to the south-west of the camp, behind the Fuel Dump, see the extreme left of the photo. These photos make everything there look very small, seeing the mountains and the glacier first hand will forever redefine your sense of size...
