La Brea Tar Pits Los Angeles CA This is a nice museum, and it seems to be geared more for school children with its displays. This is the Lake Pit with models of the animals. This lake is left over from asphalt mining operations in the late 1800s. Back then the tar from La Brea was used to seal roofs and roads. Today, the lake’s bubbles, sheen and stink come from a deep underground oil field, which also produces patches of tar on the ground. Harlan’s Ground Sloth. All of the animals displayed in the museum lived and roamed around the Los Angeles area in pre-historic times.
