Arctic Lupine and Arnica
The purple flowers are Artic Lupine - Lupinus arcticus. The yellow flowers are probably Mountain Arnica - Arnica latifolia, or Hairy Arnica - Arnica mollis - apparently the Arnica family hybrids easily.
Blowing Hairy Arnica
I believe the yellow flowers are Hairy Arnica - Arnica mollis. I've always like blowing flower pictures, but you have to find the right combination of bright flowers and dark background.
