Great, i just love forest shots.  I shoot them all year long and I think i'm going to make it my next book project.  I've done three books already, and they are fun.  I think I'd like to have just a "forest" book. . . 
I have my shot in a landscape to, but chose the portrait to post.  Ive been back to shoot that spot a couple times but cant catch the light. . . the leaves are about 50% gone now in Glacier park, we have had a lot of high winds, some snow and lots of rain, it's culminated in a typical fall - leaves start to change = wind blows them off before they get "ripe."
