To add some new ones: 

-Iron Mountain (San Gabriel Mountains, CA): 14 miles, 7000' gain round trip, no water. The last 2.5 miles gain 3500' to the top, and the entire route is exposed. This one is a roller coaster for sure. 

-Villager and Rabbit Peaks (Anza Borrego Desert, CA): ~21 Miles, 8000' gain. This one is in the middle of the desert, so again no water, and full exposure.

-Great Range Traverse (Adirondacks, NY): 26 miles, 9000+' gain. Get the best that the 'Dacks have to offer in this hike over several of the ADK High 46. There are a few optional side peaks to add some distance and gain.
