Yeah after a 24 mile horse back ride in the Rocky Mountains you' ll never want to see another horse for the rest of your life.[]

You can get a lot of gear in under the 50 pound mark. I am asuming that the " outfitter" is providing things like food, shelter, cots, cooking gear, and things like that.

Make sure you take plenty of and a variety of socks with you and Clothes for all weather conditions. First aid kit especially being on horses for 24 miles. All on your normal hunting gear like knives, sharpeners, rope. Emergency things like water proof matches, space blanket, flagging tape, compas, small mirror.

You probably won' t need the frame pack with an " outfitter" so a fanny or day pack will do. Walmart has ones with a hydration bladder built in so you can carry water with you,

A " shooting stick" can easly be made from a small tree limb if you really want one when you get into camp.

Remember that some things like your knife, one pair of boots, one set of clothes you will wear on your body.

Get a list from your guide of things that they provide so you won' t be duplicating gear for no reason. They may provide things that you would normally provide yourself on a hunt.
