 AA2139'DESCRIBED BY BUREAU OF LAND MANAGEMENT 1993 (MDL)
 AA2139'THE STATION IS LOCATED ABOUT 40 KM (24.85 MI) NORTHWEST OF BELLE
 AA2139'FOURCHE, SOUTH DAKOTA, 1 KM (0.60 MI) WEST OF THE ALBION ROAD, AND
 AA2139'JUST SOUTH OF AN EAST-WEST FENCE LINE IN OPEN ROLLING TERRAIN.
 AA2139'OWNERSHIP--UNKNOWN. TO REACH FROM THE INTERSECTION OF US HIGHWAY 212
 AA2139'AND US HIGHWAY 85 ON THE NORTH SIDE OF BELLE FOURCHE, GO NORTH ON US
 AA2139'85 19.15 KM (11.90 MI) TO THE ALBION ROAD.  TURN LEFT, NORTH, ON THE
 AA2139'ALBION ROAD FOR 4.35 KM (2.70 MI) TO A Y INTERSECTION.  TURN LEFT,
 AA2139'NORTHWEST, ON THE ALBION ROAD FOR 23.2 KM (14.40 MI) TO A GATE ON THE
 AA2139'WESTERN SIDE OF THE ROAD, AT A PIPELINE CROSSING APPROXIMATELY 0.15 KM
 AA2139'(0.10 MI) SOUTH OF THE MONTANA-SOUTH DAKOTA BORDER.  TURN WEST THROUGH
 AA2139'THE GATE ALONG A TRACK ROAD FOR 0.8 KM.  THEN TURN RIGHT, NORTH, FOR
