La Brea Tar Pits & Page Museum in Los Angeles

A pool of black tar in the middle of a green city park is an unexpected sight in Los Angeles, but the famous La Brea Tar Pits have provided a treasure trove of archeological finds for the nearby George C. Page Museum. Excavations of the prehistoric site have resulted in one of the largest collections of Ice Age fossils in the world. The oldest of the approximately 100 tons of bones hauled out of the pits date back 38,000 years. Complete skeletons of animals like saber-toothed cats, dire wolves and mastodons are on display in the museum. In the Paleontology Laboratory, visitors can watch scientists working on the latest finds.
