When John Muir visited Glacier Bay in the latter part of the 19th century, he discovered one of these orchids and fell to his knees and wept, overcome by the sheer beauty of the plant. There is some doubt about the taxonomy of this plant, but it is commonly referred to as mountain lady slipper. Unlike the calypso orchid, it seems to be found only in the Glacier Bay drainage, and it is especially abundant on the limestones of the middle-west side. Photographer: Sean Neilson
