Sunstone is litterally up the hill from Chair 15 / Eagle Lodge (201 Juniper Springs Dr.) and just  uphill from Juniper Springs Lodge.  It was Intrawest's 2nd development  in Mammoth and built in 2000.  It's one of the true ski-in/ski-out properties in Mammoth as you actually ski DOWN to the chairlift.
    
Suntone offers a fitness room, pool, spa, ski  lockers, and 'hearth room' with a coffee cart on busy weekends.   Sunstone has 3 floors of rooms and heated underground parking.  Views are spectacular for most east facing units as they look down over Juniper Springs and have expansive views towards the White Mountains and Crowley.  West facing units typically have ski slope and Mountain views and some offer fantastic views of The Crest.
  
 HOA dues include all utilities except telephone, just like Juniper Springs Lodge.  There are 1, 2 and 3 bedroom floorplans available.

Summertime visitors benefit from the paved trail down along  the Valentine Preserve and out to the Snowcreek Meadow.  The Lower  Juniper mountain bike trail also lets out right next to JSL.
