Far Left: Quarry/Cuting Configuration "C" - Duluth Complex Gabbro, Mesabi Black quarry, Lake Ct., MN

Stone Landscape Elements 2 @ 8'-6" x 6'-0" x 7'-6" anorthositic gabbro (Duluth Complex) quarry blocks cut and variably surfaced.

NOTES:
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).

GPS, depth data and geologic context for the blocks will need to be gathered - this data will form part of the inscribed text on the slabs in addition to the numbering system refered to above. A photographic record of the cutting and removal of the blocks should be done if possible - use approx. 30% overlapping of images of Block(s) in Loaf Wall to create site panorama .

Instruments used for 6-Satellite GPS survey by Bear Island Surveying, Ely, MN for Latitude, Longitude and Altitude of each slab or block to be installed as part of Site Index, in the East and West CALA Gardens. Mesabi Black Quarry, Lake County, MN, May, 2004. Measurements were used to construct the Quarry Block Diagram (far right image) and determine an accurate quarry site position to be etched into each block for SITE INDEX.
