* Indicates the wildflower is currently in bloom.

From Sevenmile Road, this route climbs along a narrow strip of USFS lands to the ridgeline of Sevenmile Hill. Know your route before going to avoid trespassing on neighboring private lands. Pull completely off Sevenmile Road as vehicles travel fairly fast down this road or know where the dirt access road (on USFS land) is to park at a wide spot uphill about 100 meters above Sevenmile Road. Watch for rattlesnakes and ticks along the route up the hill.

Weather: Partly cloudy skies early turning to hazy in the afternoon. Temperatures in the upper 50s. Winds light. A very comfortable day except for a cool breeze from the northwest at the top of the ridge!

Sevenmile Hill (via USFS Right of Way from Sevenmile Road)......April 20, 2014 - Sevenmile Hill 04-12-2015

Flower-filled slopes adorn Sevenmile Hill on April 20, 2014 in the photos at left. Carey's balsamroot (Balsamorhiza careyana), harsh paintbrush (Castilleja hispida) and Columbia Gorge lupine (Lupinus latifolius var. thompsonianus) are shown prominently in bloom. The photos at right show Sevenmile Hill on April 12, 2015 (when wildflower bloom was about 3 weeks earlier than 2914) showing the effects of the Rowena Fire from the summer of 2014. The lupines and desert parsley are coming up well as are the annuals. But the balsamroots were set back enough by the burn that only a few plants appear to be blooming in 2015, hence the lack of yellow color except in places spared by the fire.
