Please be aware that shelters in Harriman State Park in NY do not have water sources. This would include Fingerboard, William Brien and West Mtn shelters. It's best to pack water into each shelter as the only other sources of water are far, downhill and always undependable. Although dry...West Mtn Shelter has a damn nice view and you can obtain water when you cross the Palisades Parkway, about 1.5 miles before the 0.6m side trail. Keep in mind the walk to the shelter is a lovely ridgewalk and worth the 0.6 detour. If you were to continue downhill past the shelter on the T-T (blue blaze) trail about 0.5 you might find water in Timp Pass...might. Hope this helps.
