EXPLANATION

Major faults—Dashed where approximately located or inferred

F2 fold—Showing axial trace of syncline (arrows pointing 

toward trough) or anticline (arrows pointing away from 

trough)

F2 fold—Showing dip of axial plane

L2 lineation—Showing bearing and plunge

Bedding/S2 intersection—Showing fold vergence

Subsurface workings—Number indicates mine level or 

designation of stope or drift

MAP OF UNDERGROUND WORKINGS, GREENS CREEK MINE, ALASKA;

F2, L2, AND S2/BEDDING INTERSECTIONS

By

John M. Proffett

2010

Grid in gray is Alaska Coordinate System, zone 1

North-south grid in black is a local surface grid of northings and eastings, in feet,

with origin located at lat 58.0234985°N., long 134.7311267°W.

Northwest-southeast grid is a local grid of cross section (XS) and long section (LS)

coordinates that are used for Greens Creek mine workings. The grid is

rotated 26.5651 degrees counterclockwise from due north

Drill hole and underground working elevations are relative to mine system; 

60 feet must be subtracted from these to give elevations 

relative to sea level.
