Clues for October 2008:
1. Lying in an enclosed basin at a 1,000-meter elevation, these sand dunes cover a small region — only about five kilometers long and less than two kilometers wide — but they are the second-highest sand dunes on their host continent, rising more than 200 meters above a dry lakebed.
2. Like several other desert dune sands around the world — including only a handful of places in the host country — these dunes have been reported to make “singing” or “booming” noises (also described as barking, squeaking and whistling). The sounds are generated by shear stress on the sands, which is triggered by wind passing over the dunes.

Answer: The Eureka Dunes northwest of Death Valley in eastern California are the second-highest dunes in North America, lying in an enclosed basin at 1,000 meters in elevation and rising more than 200 meters above a dry lakebed. Like the dune sands in several other deserts (including Hawaii’s Barking Sands and the Booming Dunes of the Namib Desert in southern Africa), Eureka’s dunes make “singing” or “booming” noises generated by shear stress from wind passing over the sands.
