Thanks for the information, and especially the picture. We're thinking of setting up camp around Long Lake, so when we come in past Cottonwood Lakes we can scope out OAP and see if it's an option. Rather not bring snow gear though, so NAP is looking quite appealing.
John, if you see two college guys around the 20th, that'd be us!
Hi MattB,
I do not think you will be able to see Old Army from the trail to Long Lake. Of course you could take a side trip to take a look at Old Army, but you will need to get to the North end of Lake 3/South end of Lake 4. The following picture was taken nearing the north end of Lake 3, and you can see that the view of Old Army is blocked. You will actually need to go around the lake and climb up to Lake 4 (straight ahead) to see the pass.

I plan on being at Horseshoe Meadows on the 19th for a short trip up to Trail Peak for acclimatization, and then early start on the 20th for Lake 6/Langley. If I can get up the chute I'll likely see you on top. I'll watch for you guys. I'll be the guy in my avatar.
See spot from where photo was taken here:
