The Mt. Eden Formation is a geologic formation in Riverside County, California.[1] It underlies the San Timoteo Formation, and preserves fossils dating back to the Neogene period.[2]
This geologic formation was initially described in 1921 by paleontologist Childs Frick,[3] who considered the San Timoteo Badlands to be split into three lithologic parts: (1) the Potrero Creek deposits, (2) the San Timoteo Formation, and (3) the Eden beds.[4] The word "Eden" was taken from a large hill of schist located just west of the San Jacinto quadrangle.[5] By 1931, the term "Mt. Eden formation" became prevalent while the term "Eden beds" fell into disuse, and the Potrero Creek deposits ceased to be considered a separate entity.[4]
