Letter from Roger A.C. Wiliams

Colorado Central – July 2002 – Colorado Central Magazine


That Tonto Mine in Poncha Pass (p. 46, May edition) would draw 109.57 million gallons of water over 25 years @500 gal/min., not 15.6 M, my hp-28C tells me. BTW I can’t read the fine print in the “Public Notice” sign on that gate in the picture.
