We can see the boards on the bottom of box 1!
Deposit 1 is the first box of Project 23 that has been opened, and it is also the largest at an estimated 123,000 pounds. From the surface to its base, the deposit is just more than nine levels or 230 cm (7.5 feet). After 3½ years of digging, we have just reached the bottom of it in grid A-1!
This grid is of the Southeast portion of the large vent deposit in the Southern end of the box. Only the non-asphaltic, non-fossil dirt was removed in this grid to expose around the asphalt/fossil sediments, providing an excellent vertical view of the lower portion of the huge vent deposit, where we have measured 4,204 fossils so far.
