In July of 1911, the superintendent of the U. S. Coast & Geodetic Survey submitted to County Clerk D. H. Saylor in Aurora, Nebraska, the report detailing the establishment of the magnetic station by H. E. McComb on June 19, 1911. The observations were made in the northwest corner of the courthouse grounds which was marked with a Bedford limestone post 7" square and projecting 3" above the ground. In the center of the post was placed a brass station marker. This marker is what is now known by most surveyors as a brass disk. These brass magnetic station markers are the earliest metallic disks placed in Nebraska by USC&GS.
