From the day my age group started into Boy Scouts, we saved every penny we could for a canoe and fishing trip starting out from the Charles L. Sommers canoe base near Ely, MN. It took years for us to save the money, but we got it.
Compared to some of the city crews up there, we were pretty comfortable about the trip. We all had a pretty good amount of canoe experience. Each person's gear fit in a 5 gallon bucket, except food. We'd cross a lake, pick up all the packs and canoes and portage to the next lake.
We met our guide, Sam. He was a UP-er and at the time I thought he was a hard-ass, I now realize he was poorly prepared IMO. He wore shorts, a ripped up t-shirt, carried no jacket or hardly any gear. He was convinced he didn't need to use Polar Pure on his water to treat it, although we all did. He was pretty lazy and had little interest in wilderness skills. He read Dungeons and Dragons type books. Shit about trolls and warlocks.
On day 4 of our week long trip, Sam caught giardia. He looked like hell. We spent most of the morning and 1 1/2 of the 2 radio batteries on the emergency radio getting him flown out. After Sam was gone, the fog rolled in. The fog got so thick in the mornings that the person in the front of the canoe was blurry to the person in the back.
We got lost. No ego here, we were lost. Dumb luck allowed me to see a boat across the lake around lunch time. The only person we had seen since Sam caught the bug. He pointed us to where we were and said "where's your guide?" Probably stuffing his fat ass with a plate full of hot chow right now. I took over navigation after that day. No one complained. I had heard of "moose muck" but whatever it was, we apparently hadn't run in to any until the last day. I stepped out of the canoe on to a bit flat rock, put on my Duluth pack and stepped off. I sank to my chest. Here I am wearing a backpack, up to my chest in crap. Lovely. I used my paddle to get my some leverage and got out.
We hauled ass and made it back within 2 hours of when we were supposed to, but there was no chatter for the whole last day, it was pretty much all business.
Far from Les Stroud stuff, but it was a learning experience. Never depend on someone else for navigation and pay attention to where you are.
