The book is called Hunt Alaska Now by Dennis W. Confer.
"Self Guiding for trophy moose and caribou".
It's been seven years since I read it but I remember enjoying it at the time.

I did an "outfitted" caribou hunt in 2000. We used Lake Clark Air and hunted the Mulchatna Herd.
It was a fantastic hunt. They dropped us out on the tundra N. of Lk Iliamna for 6 days and nights with all the food/tent/cooking stuff/cots/lanterns etc. We just needed our personal gear. It was a lot of fun and the two of us shot 4 nice bou and a lot of ptarmigan. We also caught a lot of greyling and trout. It's a little spooky with the brown bears out there but that just adds to the adventure. I will bring my son on that hunt when he's old enough.
