I think most of the good lures have been mentioned. Crappie tubes and power trout worms wacky rigged work good too. Flat fish and phoebes are produces.
Super Duper lure. Behind the bubble, elk hair caddis dry, olive quill nymph wet. Black/yellow Marabou @ ice out, or woolies. Cast it onto the edge of the ice, Pull it off, let is start to sink, get ready to rrrrrumble.
Not high altitude but a fun canoe trip this weekend. Split shot sinkers were valuable to help cast, flies worked, mepps spinners, wedding band and a lure called an Apex.
