Call of Cthulhu scenario

So recently bear hunters discovered a huge pot growing operation in a remote national forest in Oregon. This got me to thinking, what if they hadn't stumbled onto a pot operation in the woods but something more sinister? A simple concept but a great scenario with a small group of hunters in an isolated canyon dealing with mythos goodness. The party is well armed although that may not help them much depend on the setup.

An alternative to the hunters that may present an interesting moral twist is to be the drug growers/guards for the operation who run into something in the woods. That allows for more isolation (noone is looking for them and they won't want to go to law enforcement) and still allows for some armaments. Since the skills sets would be more varied it might also make a better party.

Off the top of my head Ithaca (sp?) and Shub-niggaruath (sp?) might be good candidates to have cults or creatures in such a place.
