I camped out by myself with the bears, mountain lions, lynx’s , wolves and coyotes on the Yukon River for a month this summer and will again 3 months this year.
The pros (guides) and gun retailers told me to carry a pump shotgun with triple ought buck AND SLUGS in a magnum cartridge loaded alternately in the magazine.
So, I bought the basic Remington pump. A large caliber pistol would be a darn sight easier to lug around all day but if a bears charging you few people they say can stay cool and make a good shot.
So far, the bears see me (and I see them) a long way off and disappear, thankfully. I hear wolves and coyotes in the very short dusk nights but have not seen any. I did see one Lynx. Beautiful animal! Hard to see!
Going to sleep by yourself is concerning. About 4 hours at one time is all I can do. Plus, you have to wear a blindfold to block out the light. That’s not a feel good thing either.
Great adventure!
