I know many have commented already, and I know my reply is redundant, but know that you are safe backpacking and hunting alone. The media and many of us over hype cougar and bear attacks, as well as violence between humans, and injury risk when solo backpacking and hunting. I hunt for 10 days solo in the Colorado wilderness for elk every year, as well as several three day trips throughout the summer and fall while hunting for other species. I just did a week in Idaho for spring bear. I have gone out solo for as long as three weeks in the Yukon too, and used to take two weeks trips regularly (family and job make that more difficult). In my younger days, I routinely did 50-100 mile solo ultra-runs through wilderness in southern Canada and northern Washington. I have dealt with cougars, bears, grizzly bears, wolves, and nothing is more scary than a mother moose with calf or drunk and poorly socialized people - but all of this you can be prepared for and confidently and safely manage with ease.
Hunting solo requires a no-******** view of actual dangers, and the personal responsibility to prepare for what you can, and genuine acceptance of the few elements you cannot control. There is almost nothing you cannot control with a little forethought (liker don't camp below loose rock faces if you are worried about rock fall). In terms of being prepared, you need a fast means of self defense (plenty of good arguments between non-lethal and lethal forms) and the training and practice to execute, as well as first aid knowledge to correctly splint and move with an injury (or treat a more catastrophic injury), extra food and water treatment in the event you are injured or lost and it takes you more time to get out... etc etc. Take a WFR course and a self defense shooting training course, these are all good starts. I still like bear spray for cougars, moose and and people.. but guns for bears. Dont wear headphones, listen to music, or do anything to distract you from your environment. Being aware is the first step in being prepared - it helps you notice where you are so you don't get lost, where you are stepping so you don't get hurt, and what is around you so you don't get attacked unexpectedly... as a bonus it helps you see more animals which makes for a better hunt and hike. Because actual danger is rare, you end up noticing more things like edible plants and more nuanced aspects of nature's beauty than things to be afraid of. Makes for many enjoyable trips.
