MINE NAME COMMENTS ON FEATURES
Royal Gorge S: Subsideence trough 400' long, 25' wide, 5' deep. Trough trends N-S and marks line of near-
No. 1 surface slopes in steeply dipping coal bed. Three pits each 50' in diameter, 7' deep occur
along trough. Pits mark shafts of former mine.
Royal Gorge *: Vertical opening. Shaft opening is 8" square and 100''+ deep; shaft appears to be intact;
No. i no access deterrent.
Reclamation of Royal Gorge Mines: The remains of these mines include three extremely
hazardous open mine shafts, numerous subsidence features and six wastebanks. Spring 1983
work included the following: The open timber-lined vertical mine shaft at the Royal Gorge
/2 mine was backfilled using a graded fill technique. The open air shaft and inclined shaft
at the Royal Gorge mine involved the placement of steel and precast concrete slabs over the
existing openings. Disturbed areas were covered with a layer of soil material suitable for
plant growth and will be revegetated during the Fall of 1983.
Santa Fe No. 3 5: Four subsidence pits. Pit over hoist shaft is 10' in diameter, 1' deep; pit over air shaft
is 20' in diameter, 4' deep; last two pits are 3' and 30' in diameter and are, respectively,
3' and 2' deep.
Simon-Smith *: Reference 2 notes that the shaft was sunk in an effort to reach the Rockvale bed, an
Shaft estimated 570' below the surface.
Smith-Tanner *: Horizontal opening and collapse pit. Pit is 10' long, 7' wide, 15' deep; formed by
collapse into mine ad it; mouth of adit itself is plugged; no access deterrent around pit.
Second adit on upper level has opening 8' wide, 5' high; goes into hillside at least 25';
partially collapsed; no access deterrent.
