Keen on the Niter Beds Exploration

[DeathValleyDazed]

Late Summer or early Fall I hope to return to DEVA and I'm keen on exploring the Niter Beds because I've seen them mentioned and photographed by various forum members. So this was mined for the manufacture of gun powder? I'd like to see if there are any traces of mining, scraping, or harvesting like the remains of the borax mining out on the flats west of Harmony Borax. 

I'm open to any of your wisdom and experience with the Niter Beds. Here's what I snatched from this forum and the Internet - four images total.
