As an added note to my earlier posting, the evaluation map copies Dave Dye did at the National Archives on the 3 Silverton railroads came into play today. The EPA's mess at Gladstone involves numerous patented claims with several ownerships and the need to sort all that out as the EPA has commenced with building a treatment plant at Gladstone for the Gold King. They have hired the US Mineral Surveyor I know to sort this out for the EPA. They will be using Dave's copy of the 1920 SG&N evaluation map as a point of reference as to who owns what, and what rights if any still survive with the SG&N's right of way in Gladstone that was established under the Railroad Act of 1875.The surveyors involved are staying in Silverton for the duration as this project has high priority and the EPA doesn't just hire any surveyor--only those who are qualified to certify federal survey questions. The EPA has stated that they are spending about $1 million a week here and I'm glad some of it is going into local pockets. And thanks to Dave's sharing these evaluation maps with me, we have been able to help out in land ownership and easement questions first with the state highway department and now with the federal government. And the SG&N was built by the Gold King to serve the mine, and its legacy still is useful in today's situation. The EPA has asked these guys to map the entire course of Cement Creek from Gladstone into Silverton and Dave's maps are of considerable usefulness in determining the federal government's claims to any of the r-o-w easements through the various pieces of private land along the route. When Ernie came in my office a bit ago and asked me what I knew of the SG&N, Dave's CD was within reach.
