Dryas octopetala
Dryas octopetala

White mountain-avens can be found in Arctic and alpine areas of Europe, Asia and North America (extending as far south as Colorado). It is colony-forming and quite common along higher elevation rocky roadsides in Jasper and Banff National Parks; mid-September is a good time to witness it in fruit en masse.

The US Forest Service provides a detailed account of Dryas octopetala (PDF). For a quicker read, Paul Slichter writes about Dryas octopetala on his wildflowers of Oregon and Washington site.

strange, I would totally have guessed Asteraceae. Strange to see such a crazy fruit from a simple flower.

Beautiful! I think this may be is the same plant (or close cousin)that has haunted me for years since I saw a mass of it fluffed over a meadow in southern Colorado while I was chasing the Cumbres and Toltec RR locomotive. But -- the plant I saw had a strong pink tint.
