Malheur National Forest
Strawberry Mt. is the 9038' peak which dominates the skyline in the 107 square mile Strawberry Mt. Wilderness to the south of Prairie City, OR. Five of the seven major biologic zones may found within this small mountain range. The western half of the range was seafloor about 200-250 million years ago. Now uplifted, reddish peridotite and green serpentinite outcrops may be found here with their unique flora. The eastern half of the range consists of ash and lava spewed from vents in the area about 15 million years ago. Ice Age glaciers carved many of the valleys on the north-facing slopes.
Good spots for viewing flowers within the wilderness include Canyon Mt. (8007'), East Fork Canyon Creek, Baldy Mt, Indian Creek, Wildcat Basin (7000'), Strawberry Mt, and the meadows above Strawberry Lake.
Access by vehicle is limited from late May for lower trailheads (and late June-to early July for the highest) to late fall due to snowfall. I'm guessing that wildflower displays for the ridgetops and shaded northern slopes normally begin in late June and these can extend into early September, at least after winters with high snowfall.
