Lewis' monkeyflower blooms streamside in Mount Rainier NP, Washington, USA.

Lewis' monkeyflower (Erythranthe lewisii) blooms pink along a stream on the Spray Park–Knapsack Pass Loop, in Mount Rainier National Park, Washington, USA. Caution: the unmaintained and unmarked Knapsack Pass trail exposes experienced hikers to slippery scree and steep snow (possibly icy), best hiked in late summer using a good GPS device, map, and trekking poles. Erythranthe lewisii was formerly known as Mimulus lewisii before DNA evidence reclassified it in 2012. It is named in honor of explorer Meriwether Lewis.
