I have wanted to visit this remote area for many years! Finally I had the time and the resources. Heather and I hiked to the 3 highest points on the dunes and measured them with the GPS to determine which is highest. Other things we did on this trip include Ord, Sandy Point, Last Chance, Chocolate, Towne BM, Tucki, and Ibex Dunes HP.
I've topped the highest dunes twice with my daugher- first time she was 2 (Jan 2010), second time she was 3 (April 2011). Next time we spend the night there, I'm going to head up some of the named peaks in the Last Chance Range overlooking the dunes...so far I've just hiked to the point west of the Crater at above 5,000 feet.
