Mammoth Area Orchids:  

Corallorhiza striata (striped coralroot), Piperia unalascensis

Corallorhiza striata (striped coral root). These normally grow in shade, but I have found them in sun along the Narrow Gauge trail in Mammoth.

Blooming: late June to July.

Sniff test: Coral roots always seem odorless to me. Alaska rein orchid has a strong pleasant aroma.
