Calypso bulbosa. The most showy of Yellowstone's orchids. There are 3 varieties seen in the park: white lip, red lip, and red spotted lip. Here are photos of the white-lipped and red-lipped varieties. Near Bozeman, Montana, I have seen a very pale variant, though not completely albino.  

Locations: Lost Lake trail from behind Roosevelt Lodge. Large colonies on the uphill side of the trail in mid-June below the last switchback en route to the lake.   Trout Lake trail (between Soda Butte and Pebble Creek campground in Lamar Valley), on the lefthand side of the lake in deep shade.   Reportedly on Elephantback trail, but I have not seen them there. 

Blooming: mid-June. Found June 11, 2014 near Roosevelt and June 15, 2014 on Trout Lake.  Wilting by late June but still there. 

Sniff test: Sometimes these have a slight perfume, other times I do not detect any fragrance. Fragrance may depend on time of day.
