Glacier Lily
Erythronium grandiflorum
Each plant usually boasts a single flower supported on a 6-12 inch (15-30 cm) long stem (unlike the 2-3 flowers per stem found on avalanche lilies), but often found growing in clumps of multiple individuals. Glacier lilies also bloom earlier than avalanche lilies or other flowers, sometimes even pushing through late-season snow in order to flower.

Lousewort, Mount Rainier
Pedicularis rainierensis
At a glance, this lousewort has a flower similar to bracted lousewort (P. bracteosa), with a curved and hooded upper lip and narow lower lobes. The yellow flowers densely cluster in a relatively short inflorescence. Leaves are divided and mostly basal. Once believed to be found only at Mount Rainier, a few individuals have been reported at Mount Baker and the surrounding Cascades.
