Both the Folsom wedge and the Clovis sediment block are being mapped in plan view. Each block has a permanent (but arbitrary) elevation datum. The Folsom wedge is gridded as a 2 x 2m unit with the 100cmN/100cmE point roughly centered on the block. The block is divided arbitrarily into directional quadrants (e.g. SW quad) based upon its present orientation. It’s original orientation is currently unknown.
