Was up at Eagle Peak several years ago. But the South Warners are several hundred miles north of the Bristlecone Pine range limits. Can't tell from photo, but my guess is Lodgepole Pine or Whitebark Pine.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
