Oceanography Fig. 1 Laguna Guatavita Crater, Colombia, looking southward, obliquely across a northeast-ward plunging anticline. The crater is breached by a stream in the northeast quadrant A large slump block can be seen within the crater and the southwest wall is deeply dissected. The crater lacks a raised debris rim and there is no ejecta blanket Photo by H. Raasveldt. sacred. It is widely regarded as the lake upon which El Dorado, the man-god dusted with gold, sailed aboard a raft while he cast gold ornaments into the water. This legend has recently received new support by the new discovery of the model of such a raft with the man-god and his retinue aboard. This artifact is now the prize exhibit of Colombia's National Gold Museum in Bogota. For four centuries, treasure hunters have scavenged Laguna Guatavita and its environs. A scuba diver reported that the lake bottom is pitted and scarred by treasure hunters. It is well known in Colombia that a grand attempt was made by Spaniards about 1820 to deepen the stream exit and thus drain the lake but landslides defeated the effort. It is virtually unknown that a draining was successfully and apparently secretly accomplished in the early 1900's by a British syndicate. After eight years of labor, they succeeded in driving a 400-m drainage tunnel. Numerous artifacts were recovered, but no gold treasure hoard. The drainage is clearly established by a 1910 photograph published in a rare German travel book (Weisswanger, 1911) which shows the lake bottom to be flat and occupied by a now drowned stream channel running across a graded plain. Evidently the lake once was naturally drained by the downcutting of the exiting stream only to be later dammed by landslides. The bottom fill plus the well developed valleys cut 304 517.
