Outfitters want to earn a decent living and have a pretty small window to do it. When the demand is high, their prices rise to what the market will bear, when things are slow, they cut prices just to stay in business and hopefully break even. Their overhead isn't getting any cheaper, nor are many of their clients interested in fewer amenities, so prices do increase over time. If you've got say half a million bucks tied up in out camps and cabins, boats and motors, maybe an airplane, along with staff who must be paid and begin work well before the first paying client arrives, to say nothing of the cost of running a full service restaurant well away from any services, how much of a return would you want on that money?
