Yes, I recognized your photograph.
I also fished in the Yukon and Alaska when I was about 16 and much healthier.
It was wonderful, I fished Big Salmon Lake ( I think thats the name )....We put in at Quiet Lake and went down a rapid to Sand Lake and then another rapid down to Big Salmon Lake.
The fishing was phenomenal. The Pike there were so wild, it's like they had never seen a fishing lure. They would attack ANYTHING you put in front of them at any time. They also would cannibalize each other, it was insane. I bet if you fall out of your canoe there, they would eat you like piranhas. lol
Also, there were many Grayling and my father caught a lake trout that must have been 50 lbs, but as soon as we got it near the boat it broke the line. It was gigantic. Biggest fish I've seen in my life. The lake trout up there have nice coloured flesh, and are very good to eat as you probably know.
anyways, yah I had fun during that trip. Also fished in Skagway Alaska but didn't catch much. The Yukon was the main attraction and spent alot of time fishing there.
I recommend it to anyone...It was a once in a lifetime thing for me, definitely the most beautiful natural place I have been, the mountains are breathtaking, the water is freezing cold, there is snow on thetops of the mountains, and the fish are plentiful and so eager to attack anything you put in......Get some motorized big canoes, trucks, drive into Quiet Lake and launch there, then it takes about 1-2 hours to get to Big Salmon Lake. You have to negotiate through some rapids and it's very beautioful there. Only problem is that Quiet lake has big waves during wind and we got stuck at a camp site for 2 days without food and beer trying to get home with no luck! haha......Water there is ice cold too so I became hypothermic on the way out of that lake because water was splashing on me. I was the front passenger

first to get hit with cold water haha.... If you go, bring the appropriate gear, maybe even a dry suit, you should treat the water there as you would ice water in a lake in the winter here. It will kill you if you fall in and can't get out quickly. I can imagine dying in that water within 3 minutes if you aren't able to get out. It is pretty cold, icy water.
Take Care!
