Washington Trails Association has a number of new hike reports that mention wildflower bloom. Most of wildflower descriptions are pretty sketchy but they might give a rough idea of what is happening on the trails. Here are excerpts:
Rattlesnake Ridge Trail, Rattlesnake Ledge, Rattlesnake Mountain, East Peak-Rattlesnake Trail — May 08, 2013 — Snoqualmie Pass — North Bend Area
There were lots of wildflowers during the second half of the descent into Snoqualmie Point.
Green Lake — May 07, 2013 — Mt. Rainier — NW – Carbon River / Mowich
Watch for Sitka spruce trees along the route in the lower valley – the only place they occur at Mt. Rainier. There’s early season wildflowers, skunk cabbage & trillium in bloom along here.
Dog Mountain, Augspurger Trail — May 05, 2013 — South Cascades — Columbia Gorge
The forest floor was rich with flowers: yellow spikes of low or creeping Oregon grape, soft white of woodland strawberry, a few triliums farther up, a few fairyslipper and lovely fairybells. Fringecup, vanilla leaf, and star-flowered Solomon’s seal. A shrub with a froth of white flower spikes (looked like Ceanothus). Even a few paintbrush and pretty yellow violet.
Oyster Dome — May 05, 2013 — Puget Sound and Islands — North Sound
The Trillium is coming out as the Skunk Cabbage is on the wane along the trail and at the lake.
Umtanum Ridge Crest — May 05, 2013 — Eastern Washington — Yakima
Many flowers blooming at different elevations, including shooting star, lupine, larkspur, sagebrush violet and hedgehog cactus on the ridge. I could not find any bitterroot in bloom. Strenuous, but worth it for the great views and all the variety of flowers.
