Satelite View

The satellite view offers a quick glimpse as to whether the MRDS location corresponds to visible mine remains.

Comment (Names): The original site name contained a derogatory word that has been changed according to Department of the Interior policy outlined at http://geonames.usgs.gov/docs/pro_pol_pro.pdf. See Chap. 3, Policy V. The revised form of the name now appears in the permanent record as the "Current" or preferred site name, and the prior, derogatory name is labeled "Previous".
Comment (General): Doug Causey - Data consolidated from DEP_ID 10283559 - a duplicate record.
