On the topic of interpolation, I wonder if other areas along the trail of the Yellowstone hotspot might be easier/better sources of lithium. I suspect Nevada makes access easier than areas in the Snake river plain. But some of those areas might be more amenable to Lithium mining with less of an impact.

I specifically went out of my way on a trip a couple years ago to check out Thacker Pass to see where this planned Lithium mine was going. Unfortunately there was thick smoke followed a significant thunderstorm as a front came through and I didn't get to explore much.
