No flower of Crater Lake National Park elicits so many inquiries form observant tourists as the Pink Monkey Flower. It is one of the commonest flowers along the trail to the lake and along the streams of the Hudsonian Life Zone. Many times a day rangers and ranger naturalists alike are asked, "What is that bright pink flower about so high that blooms along the trail?" It is a pleasure to be able to say definitely that it is the Pink Monkey flower for there is no other pink flower "about so high" and "blooming along the trails and streamsides."

There are those who prefer to know the flowers by their technical names, and by those the Pink Monkey Flower is known as Mimulus Lewissi.
