I have had some pretty good luck up above tibble tossing small spinners such as a raindbow pattern roostertail or #1 blue fox vibrax for browns. As far as Tibble goes try the same or even a small rapala in rainbow pattern . As far as fly's go maybe a streamer such as a bugger if they are not rising. I am curios as to what was hatching when you were up there. Great to hear that you made it out in between snow storms.
Fishing! enough said.
