Ishi,
There has been some good advice given here and surely, a lot to consider. So I really don't have much else to add. BUT........I do have some opinions about a few things, based on experience, that I would like to share with you for your consideration.
One thing that is hard to wrap your brain around when you are pouring over topos in your living room in NY, or in my case, Texas, is the sheer size of the country inwhich you'll be hunting. It is very daunting. And with that in mind it is very possible, after all your hard research, to hunt for a week and not see a fresh track much less an actual elk.
I've been elk hunting for 25 years and I've done it every which way there is. Group hunts, DIY packin, guided and drop camps. My suggestion to you would be to strongly consider doing a drop camp. It's the next best thing to using a guide because, hopefully, if the outfitter that hauls you in is worth a darn they are going to put you in the middle of elk country. They can give you tips and point you in the right direction to get you started.......the rest is up to you.
I may be wrong but I sometimes sense an undertone in some of the elk hunting advice given that if you don't do a DIY hunt you're not a real man or a real hunter. Now....if you want to tag along with an experienced elk hunter....great! Do it. But if that doesn't work out.....go with an outfitter. It will be money well spent in the long run. There seems to be a miss conception about having a guide or having a guide haul you in. That you're guaranteed and elk. WRONG!! Couldn't be farther from the truth. It's still hard work and hard hunting. But...you can learn in one week spent with a guide what it would take you years to figure out on your own. Guys like you and I don't have the luxury or time of being able to scout out an area to hunt. Or at least I don't. That's where an outfitter can help. And you can do a drop camp very reasonbly.
Also.....elk hunting is not a group activity. In my opinion, more than 4 hunters in camp is too many!!! Two is best!!! And make sure that if you do use an outfitter and go the drop camp route that they limit the number of camps in a particular area to one camp....ONLY!!! I looked into doing a drop camp in a area I used to hunt about 10 years ago whereby we were the only camp. Well the ownership has changed and the new guy running the outfit is putting 4 drop camps in the same area that we use to hunt out of 1 camp. That just won't do!!!!!
Too many people is too many people. A great spot can get screwed up real quick when there are two many guys tromping around. The elk can move over 2 or 3 drainages and you won't figure it out until it's too late.
And one last thing......spend the extra money to get an either sex tag. In my personal experience, I've had way more close encounters with bulls than with cows.
Good luck!!
Brett
