Subalpine Spiraea, Spiraea densiflora

Growing along the trail on the way to the summit of Silver Star Mountain in SW Washington, these low-growing flowers are similar to the more common Hardhack, Spiraea douglasii, whose flowers have a more cone shaped overall appearance as opposed to the Subalpine Spiraea that has a more flat-topped overall appearance.
