From high above treeline, this view looks west across Diamond Lake at the broad dome of Mount Bailey. Bailey has several excellent ski runs, including the East Bowl at left and the Northeast Face at right, offering terrain over 40 degrees steep. A snowcat-skiing operation runs on Bailey during the winter and early spring, offering easy access to fine powder (and Cascade concrete).
