"Asphaltum or tar (brea in Spanish) has seeped up from the ground in this area for tens of thousands of years. The tar is often covered with dust, leaves, or water." (Source)
Brian remembers these life-size models of mammoths. The poor mother has been caught in the tar! A sign posted by the pit states, "These seeps became unique death traps for countless Ice Age mammals and birds, making Rancho La Brea the world's richest deposit of Ice Age fossils. Over 100 tons of fossil bones have been recovered."
See that colorful house in the distance?
The crocheted facade was awesome.
Who knew I'd find this at the La Brea Tar Pits?
