2) Volume refers to the amount of crushed stone needed in each hole, minus the volume of the slab. The total volume of crushed stone needed for stones 1-14 is 37 cu.yd. This assumes zero volume for the Geotextile, so it is a generous estimate that will be offset by loss of stone in the field.
3) Hole location refers to the offset in feet to the left (-) and right (+) of the wooden stakes at the Sunwheel located 60' from the center. These stakes are at the azimuths listed, measured clockwise, starting from North (N -> E).
4) The length of Geotextile to be cut for each hole assumes that the fabric will be wrapped around 2' of crushed stone over the shorter dimension of the hole, with a 2' overlap on top.
5) The weight of the crushed stone totals 51 tons, or 102,000 lbs.
6) Numbers revised 11/21/00.
