Thanks, Rich. My father used to summer at Brietenbush Hot Springs 10 miles south of your Sisi Butte suspect. Way back in 1911/15. He wrote a military march named after the area.(www.guidodeiro.com). These potential impact sites you kindly gave coordinates to are a bit to indistinct and aged for my less learned eyes,but I do see what your talking about.
