Long Description:
MILE HIGH 2003, CO, is a survey disk mounted vertically in the face of the 13th step of the west stairway entrance to the Colorado State Capitol building in Denver, CO. It is stamped STATE OF COLORADO 2003 MILE HIGH MARKER 5280 FEET ABOVE SEA LEVEL NAVD88, and depicts mountains and clouds. Handheld coordinates are N39-44.354 W104-59.112. The “mile high” spot was set originally in 1909 by “Professor Herbert A. Howe”, and marked with a tablet on the face of the 15th step (from the bottom). Over the years, vandals stole four separate “mile high” tablets. So, in 1947, the capitol building superintendent had “ONE MILE ABOVE SEA LEVEL” carved in the face of the 15th step. In 1969, students from Colorado State University determined that the original “mile high” mark was inaccurate. They installed a “geodetic survey plug” (disk) at the corrected location, the face of the 18th step (ONE MILE HIGH 5-12-69). In 2002, “engineers” determined that the new NAVD 88 datum yielded a different location for the “mile high” mark. Personnel from the Professional Land Surveyors of Colorado, Metro State College and the Colorado Department of Transportation worked together to determine a new “mile high” location and, in September, 2003, mounted a survey disk in the face of the 13th step. None of the three “mile high” marks are in either the Geocaching or National Geodetic Survey databases. To reach, go to the west stairway entrance to the Colorado State Capitol building in Civic Center Park at the intersection of Colfax Ave (also known as Business Interstate 70 and US Highway 287) and Sherman Street. Recovery of this station was first logged at the Geocaching datasheet for intersection station DENVER STATE CAPITOL DOME, PID = KK1709
