I am familiar with 18. To the best of my knowledge, there is no legal motorized vehicle access in this area. It is mostly drained by Fish Creek to the south and west, with some smaller tribs. You are looking at long uphill pack-outs from the best habitat to the access, which is on the east.
It is OK moose habitat, with narrow willow bogs down along small creek beds. There isnt much for swamps, ponds or lakes. I have seen fair moose numbers, but havent seen what most would consider a trophy moose. Lava Mountain area is famous grizz habitat. I havent had any problems with them, but apparently others have. I have noticed a huge drop in rigs parked at the trailheads over the last 5 years.
Bottom line is you will probably need horses to fully hunt the area. You will see moose, but probably no bad boys.
