 Those duck decoys are quite impressive, and while they are held by the Smithsonian Museums, some items are at the Humboldt Museum in Winnemucca. The decoys were probably used here, perhaps when the dry lake bed was once a wetter place. The 330-mile-long Humboldt River terminates here in this vast dry lake bed. The Humboldt sink looks like a massive lake at some points of the year, but I imagine at that time when they were around, it was much more wet.
