Dark throat shooting star

Gordon is correct. To be more specific, it is a Dark-throat Shooting Star (Dodecatheon pulchellum). There is also a white variety of this flower named, what else, White Shooting Star (Dodecatheon dentatum), that is reputed to grow in the Northwestern US, Southwest Canada and into the Rocky Mountains. Your variety is a bit more hardy and thrives from northern Alaska all the way down the coast to the south of Mexico. Nice picture - I was able to identify the flower right away, but verified it with The Complete Illustrated Encyclopedia of Wild Flowers and Flora of the Americas by Martin Walters & Mick Lavelle.- c. 2007. Thank you for your efforts. Sincerely, Deb G. - Uncasville, CT
