We have over 20 trenches dug, 5 of which are open at any given time. We try to dig one a day each, but the rocky, clay-filled lower strata make the going tough. The floatation hose broke the other day, so for two hours I sat and held it in place to get some work done -- no trip to the beach that day! Our new trenches are producing a ton of soil samples -- we have had to do 9 a day and are still a bit behind.
Among our new trenches is a new cave trench! The soil there is vastly different due to erosion of the rocks above, sediment and calcite dripping from rain water and the number of uses it has served for goatherds. We have four grids now -- A, B, C and T, the cave grid. We're hitting a lot of coral and bed rocks, but now the name of the game is to move as much dirt as possible and find where the trenches are sterile, to determine the size and shape of the living area.
