Amateurs. Building an elaborate shelter, instead of procuring adequate food income. Taking the wrong gear. Not knowing what to do with the gear, or in what order to do it. They had the option (now removed) of taking a 2 gallon metal bear canister, and instead took a 2 qt pot, so what does that tell you about what they know?
You dont want an axe, ferrorod, big saw, belt knife. Instead, you want a Cold steel shovel, a Silky saw blade, held in the visegrip of a modified Crunch multitool. 2 picks, not 4. The 2 that nobody knows to take will feed you just fine. A PARACORD hammock, and a PARACORD gillnet. Unravel them, remove the outer sheathing and weave 100m of 6 ft wide, 3"mesh netting. You can weave 200 sq ft per day, and each day, hang the previous day's production as a gillnet.
When all done, you'll be able to close off an entire cove. Bait the head of the cove with fish guts, as the tide comes in, and as the tide starts out, close off the mouth of the cove with the net. Using poles driven down into the mud, move the net towards shore, trapping the fish where you can dip net them into a deep pool, and pen them up there, enabling you to spear a day's supply of fish in 15 minutes, any time that you wish. The penned fish will serve as bait for seals and bears, too.:-) Make a ladder, and a tree platform-blind. bait in bears and arrow them. Boil offf seawater all day, every day, for a week or more, recovering enough salt to preserve 100+ lbs of fatty bear meat.
Take one of Chief Aj's slingbows, with 4 of the 6 arrows featuring 4 tined fishing heads. You can swiftly convert those into 32 fishhooks. Take 8 treblehooks and the line. bait them with roasted cambium, set them on small log rafts, for ducks and gulls. Tie a 3 lbs drowning rock about a foot from each hook, so that the ruckus ends in 1 second flat, and the suffering is ended in 10 seconds or less
Make a big, wooden mortar and pestile. Use it to juice 20 lbs of kelp every day. Have to soak the kelp in freshwater and boil the resulting juice, but it's 200 carlories fish and game offer no carbs. per hour of carbs. can't eat enough kelp, it gives you the trots. It's only got 50 calories per lb. gotta juice it.
