Sorbus scopulina (Rowan Tree, Mountain Ash)
Rosaceae (Rose Family)

Montane. Woodlands. Summer.
Cimarron Trail, Uncompahgre Wilderness, August 22, 2004.

Rowan Trees are not commonly noticed in the mountains of the Four Corners area, but they are noticed along city streets and in front yards where they make a handsome splash of color.  In montane woods, they are often small, multi-trunked trees that only attract attention when they get their bright berries and fall color.  Once one learns the tree's appearance and forest habitat, it suddenly becomes more common.  Isn't this so often the case?

Linnaeus named this genus in 1753.  "Sorbus" is an ancient Latin fruit name and "scopulina" means "of rocky places".  Edward Greene named this species in 1900.
