I was having some difficulty with this ID here on iNaturalist, but, after some searching online, I’m fairly confident it’s A. nissenana. Observed at ~ 8,400’ along a water source just off the Ralston Peak Trail in the Eldorado National Forest. Like most manzanitas I’ve observed, the leaves on this specimen are alternate and upright; however, instead of being tough & leathery—again, like other manzanitas I’ve observed—these leaves are downy, pliable and sage-like. I really should invest in the JML field guide to the Sierra. I’d love to know if you disagree with my species choice. I’d also love to know if there’s another field guide you recommend. Thanks!
