No, nothing on Cresatin. But, as to refridgeration... when San Diego
demolished the Aztec Brewery, they found the ground frozen 200-feet below the
building. No one in the planning or environmental process anticipated that
problem, so there were no provisions for archaeologists to be present when
they bulldozed 200-feet down to remove the ice. The massive crater was loaded
with artifacts from the top 20-feet.
