That's kind of surprising. Jeffrey pines are most common on the eastern side of the Sierra crest where they will grow down to about 6,000 feet. I wouldn't have thought of them as growing well at over 12,000 feet, but I guess they are already well adapted to harsh growing conditions, and maybe now with less snow, it's possible for them to get a foothold. Jeffery Pines also grow on top of San Benito Mountain in the coast range (5,267 feet) where they grow in serpentine soils that are toxic to most plants.
