Been wanting to find a good plant identification resource for a while, found this forum and you folks seem friendly.
I apologize if this one is too easy, but with my lack of plant knowledge, 30 minutes of googling could not find a definitive answer.
This was a photo taken 2 weeks ago (July 2016) at about 9,000ft elevation in Yosemite National Park(eastern CA). These purple flowers were very common, and from google results it appears to be some kind of Lupine? Is there a subspecies that is endemic to the Sierras?
