I'm still plugging through the photos from last week's hiking trip; many are fuzzy, but perhaps identifying them will help me get better photos another time. This one's Diapensia lapponica and it seemed to be abundant above tree line.
Among its most noticeable features is that despite brisk winds, the spent flowers often end up upsidedown on top of the clump.
