In 1972, before the Stewart-Cassiar Highway was finshed, I spent the fire season on Bell Lookout, above Bell-1 crossing; this was chopper access only, "B" machines and REAL wilderness in those days. I was there for 86 consecutive days, alone and with ONE mid-season supply trip. It remains one of the highlights of my life as I was 26 and I LOVED it, even the vile weather and bouts of loneliness, I read Joyce's "Ulysses", a lot of Ezra Pound, Eliot and various biology tomes and hiked all over those gorgeous mountains whenever the rain allowed me to leave the lookout cabin.
I DID walk over to Hyder AND sat in that "throne" and drank the "Everclear" shotglass full with beer chaser, that was being "Hyderized". I used to really enjoy drinking and taverns like that, the "Glacier Inn", IIRC, and could handle my share of "hangover juice".
The "Grande Duc Mine" near Stewart was still going and Hyder was a busy little place, VERY fine folks and I still, 35 years later, remember "Dave" the bartender, a helluva nice, big bear of a commericial fisherman who would buy US about every third round....you would NEVER see that in a BC pub!
I was last in that country in 2005 and my buddy and I "might" be up there again this coming summer. We are trying for a Dall's Sheep draw north of there and "hope" to get a week when he is free of work to drive up and backpack into a couple of drainages; maybe go to Whitehorse, if his schedule permits.
The effectiveness against moisture seems to be all "in the head",.......
