I just came across this in a search but they look like a species of lupine, if i were to guess from Alaska, and the coloration since its hard to tell many diagnostic details, looks like Lupinus nootkatensis :3

The other options are Lupinus polyphyllus or arcticus, but nootkatensis looks closer with that coloration. Lupine species are beautiful and there are tons of species that grow in warmer climates!

Oh! so Lupinus nootkatensis- interesting lol XD
Though I do say, this only adds to the beauty of Alaska. Her beauty is something you one will need to witness in person. The air, mountains, trees, soil- I can only describe it as a siren calling to you, wanting you to stay.
