[Wildflower Bloom in Central and Eastern Oregon: 2011]

Roads End Trail #201A & Onion Creek Trail to Strawberry Mountain

Strawberry Mountain Wilderness

August 18, 2011

Rydberg's Arnica: Arnica rydbergii

Rydberg's Arnica: Arnica rydbergii

The snow has finally cleared off the full length of the Roads End Trail #201A and along all of the Onion Creek Trail. Access to Strawberry Mountain from Strawberry Lake is still obstructed by a tall east-facing snow cornice just downhill from the junction where that trail joins the Onion Creek Trail. That route probably won't be fully open yet for at least another week although hardy hikers can find a route through the snow by careful observation to find where the snow is narrowest. The difficulty will be for those who have heavy backpacks who may be squeamish about climbing or descending a steep snow patch with a pack on.

The bloom along the mile length of the Roads End Trail #201A as well as the Onion Creek Trail are both nearing a peak, perhaps lasting another week or two depending on temperatures and chance of any rainfall.
