Where is Soldier Bar?? I have been into Thomas Creek and Indian Creek. I see Little Soldier Mountain right there, but I dont see a Soldier Bar landing strip.
Anyway, we flew out of a place in Challis, I wish I could remember the name, but cant right now. I think there's only one or two in Challis, so shouldn't be hard to narrow down. You can probably fly in from over in McCall, much close drive for you.
I was in there in....early October I think it was, sheep hunting. May have been late September. We were on the west side of the river between Indian Creek and Thomas, hunted up Marble Creek alot.
All I know is the country is huge and there really isnt a TON of game, so you do have to cover some ground. The elk will definitely be several thousand feet above the river, so you have to consider hiking up and spiking out to hunt them. We commonly saw mulies down at the river, so thats not as big a deal. If you go late when they are rutting, I'll bet you get some action.
I just located Big SOldier mountain, Soldier Creek, and Soldier lakes on the map. that must be in the vicinity of where you are going, way upstream from where we were. It almost looks like you could hike in from the road and hunt that country?
Anyhow, not much info for ya, but I wouldn't blow 338 on an elk tag "just in case" unless you flat had the money to blow. I think a guy would be doing real good to kill a bull in there if he was strictly hunting for elk, especially on foot. However, if you dont buy a tag and a 375 bull walks out broadside and laughs at you.....dont come looking for me!
Honestly, I was in there for about 6 days, hi and low, glassing all day for sheep. NEVER saw an elk. Did find a nice shed though.
Good Luck, sounds like you've got a little adventure planned! I too am hunting Idaho this year!
