Well, I didn't do the "get dropped off in the bush by a bush-plane routine", but I did visit Alaska for a couple of weeks with the GPAA at their claims up near Nome, an experience I'll never forget. Saw Muskox, bear, giant whale skeletons, storms on the Bering Sea, the wonder of thousands of Salmon running upstream, miners camped and living on the beach, the mysterious glory of the Midnight Sun, an old abandoned bucket-line dredge, abandoned placer diggings, active placer mining with the gold running from the top to the bottom of the large sluice, the miniature majesty of the flora of the tundra, and lots of other prospectors enjoying the incredible beauty of Alaska all while getting some decent beach gold.
When I was there in the mid-90's, I had a buddy that had found a rich spot on the beach in an isolated area, and I recovered some really nice beach gold, hefty weight worth of it, by high-banking, lots of nice gold hiding in the ruby sands at that spot.
However, for me, the real treasure was the experience of just being in Alaska, low risk of dying when you go with a group, but you'd miss out on the adventure of being isolated and the risk of bear and other predator encounters. (Small chance of that where I was as many miners were heavily armed.)
The fishing was spectacular, caught so many salmon I got bored and went for a hike--true story, a first for me as a fisherman!
I have been in many remote areas prospecting before, and I've had many bear encounters, some hair-raisingly far too uncomfortable, but it's an adrenaline boost you'll never, ever forget, if that's your jam.
I've been briefly stranded in the wilderness as well, not something I wish to repeat, as between the blood-thirsty bugs and the ever-present risk of apex predators, I'm happier with a peaceful coexistence if safety and a fool-proof exit plan.
If you do decide to do it, follow the sound advice you've been given and go for the grand adventure, and if not, maybe try a tamer wilderness experience with a safety-valve that gives you a lot of the sizzle and aroma without the risk of losing that delicious steak.
All the best,
Lanny
