Columbian mammoth
The 1952 Mid-century modern style Observation Pit in the park, a repository for large Ice Age fossils from throughout the tar pit area, reopened in 2014 after being closed since the mid-1990s. It is part of the Page Museum's new Excavator Tour. The Pit 91 fossil excavation, also reopened in 2014 for excavations and public viewing, had closed in 2006 to focus on fossils newly uncovered during excavation for LACMA's new subterranean parking garage in the park's western area. The skeleton of a near-complete Columbian mammoth was among the excavated discoveries there.
