Edward Herbert Thompson Most of the major findings in the cenote were made under the supervision of
Edward Herbert Thompson, who began
dredging in 1904. Much of what is known about the dredging process is derived from Thompson’s personal notes. Thompson received money from
Stephen Salisbury III to help him buy the Chichén Itzá excavation site and explore the cenote. Much of Thompson’s findings and research can be found at the
Peabody Museum at
Harvard University. A bucket attached to a pulley system was used to dredge the cenote. Much of the beginning work consisted of clearing debris and fallen trees on the top of the water. Leon Cole, a colleague of Thompson, once recorded in his journal, “they made ten hauls in the morning and six or eight in the afternoon.” People would search through the buckets of water looking for artifacts and categorizing them accordingly. Unfortunately, there were several reports of stolen artifacts that could never be found. Thompson decided to take a break from dredging after Salisbury died. A host of problems, including the
Mexican Revolution, and financial issues began to hinder the work effort and damage the morale of the workers. Thompson’s house in Mexico was also burned down, and one of the chests in which he kept his notes and data was destroyed in the fire. By 1923, Thompson was officially done working on the cenote.
Diving in the cenote In 1909, Thompson decided to dive in the cenote to explore the floors, assisted by two Greek divers from
the Bahamas. He reported limited visibility due to the murky water, and many shifting rocks and trees made the dive hazardous. Thompson found a layer about thick of blue pigment that had settled on the ground of the cenote. He described the bottom as, “full of long narrow cracks, radiating from centers as if the glass bottom of a dish had been broken by a pointed instrument. We found down in the cracks and holes a grayish mud in which were imbedded the heavier gold objects, jades, and copper bells in numbers.” He later proudly proclaimed, “I have at last personally trod the bottom of the Cenote.”
Exploration under the Mexican authorities In 1961, the
Instituto Nacional de Antropologia e Historia (INAH) in conjunction with the
National Geographic Society and
Club de Exploraciones y Deportes Acauticos de Mexico (CEDAM) conducted another expedition into the cenote. Some of the notable discoveries included an inscribed, gold-sheathed bone, a large
chert knife with a gold-sheathed wooden handle, and wooden ear flares with jade and turquoise mosaic. In 1967-1968, Norman Scott and Román Piña Chán led another expedition. They tried two new methods that many people had suggested for a long time: emptying the water out of the cenote and clarifying the water. Both of these methods were only partially successful. Only about of water could be removed, and the water was clarified for only a short amount of time. ==Objects found in the Sacred Cenote==
