Like the La Brea Tar Pits. Very interesting place if you've never visited. Many Pleistocene fossils in a nice museum.
I have heard and read about the La Brea Tar Pits since I was a kid but have not had the fortune to visit it. Someday maybe.
I was surprised that the tar pits were in an area of less than five acres and the digging was primarily around 50 feet by 50 feet straight down only another 50 feet. The most interesting were the skeletons that were reconstructed in the lab and on display.
