Alpine Sandwort

Cherleria obtusiloba is a perennial alpine herb known by the common names alpine sandwort and twinflower stitchwort. It is native to the mountains of western North America from the High Sierra of California to the Colorado Rockies north to Alaska, and to far northeastern Russia (Magadan, Kamchatka, and Yakutia). This is a low plant forming mats or clumps and bearing small thimble-shaped flowers with curving white petals.
