Quarry Block Diagram and Geographic Measurements used for Indexing of East and West CALA Gardens Slabs and Blocks, Mesabi Black Quarry, Lake County, MN, May, 2004

Latitude, Longitude and Altitude of each slab or block from 6-Satellite GPS survey by Bear Island Surveying, Ely, MN
Block No. 1 used for West Garden, Block No. 2 used for Rosetta Stone and East Garden, Block No. 3 held in reserve. Broken material from blocks and excavation rubble planned for use in North Garden.

NOTES FROM ORIGINAL CUTTING DIAGRAM:

The entire assemblage when cut from the Loaf Wall, should be marked with East-West/top-bottom orientation, GPS location (altitude, longitude and latitude) and to facilitate text numbering/indexing system described below.

Numbering: E-1, E-2, Rosetta, W-1, W-2, etc., are shown below for reference and are the numbering system to be used at Cold Spring Plant to keep cut slabs in geologic order and orientation and refer to etched text indexing system (final text to be finalized ASAP); blocks East of the "Rossetta Stone" will be placed into the CALA East Garden in order (Rosetta to East, E-1 to E-10), those West of the "Rossetta Stone" will be placed into the CALA West Garden in order (Rosetta to West, W-1 to W-21).
