Observation Pit
The observation pit at the west end of Hancock Park is a partially excavated deposit of fossils and bubbling asphalt enclosed in a circular building that first opened in 1952. Depth of excavation 12 feet.
Located on the site of Pit 101, the display in the Observation Pit demonstrates what the fossil localities looked like while being excavated. This building was dedicated in 1951 to the memory of Dr. Chester Stock, the Caltech professor and County Museum curator, who personally described many of the different kinds of fossil mammals recovered from the tar pits.
