Mammoths of Anza-Borrego Desert State Park

Mammoths were widespread in Anza-Borrego Desert State Park during the late Pleistocene, where more than 80 proboscidean fossil localities have been documented, including mammoths of the genus Mammuthus.
The following text is reproduced verbatim from Fossil Treasures.
It is difficult to imagine that, in the not-too-distant past, herds of elephants roamed an area that today is a desert. What now is Anza-Borrego Desert State Park (ABDSP) once was the home of several species of elephant-like proboscideans.
The skeletal remains of these lumbering beasts are among the most important of the fossils recovered from the Park, due in part to the scientific impact they have had on the field of vertebrate paleontology.
Over eighty localities yielding proboscidean remains have been recorded in ABDSP. This makes it one of the most productive proboscidean fossil localities in North America. Although most fossils are very fragmentary, some sites have yielded nearly complete skeletons and tell us much about the living conditions and the environment that supported life and brought death in ancient Anza-Borrego.
The proboscideans from ABDSP are represented by two separate groups, the gomphotheres and the mammoths. The earliest gomphothere remains from the Park (Gomphotherium) may be as old as 9 million years (Jefferson, 1999), the latest (Stegomastodon) 1.4 million (McDaniel and Jefferson, in press). Thus, the gomphotheres persisted in this area for about 7.5 million years. Mammoths (Mammuthus) crossed the land bridge from Siberia and arrived in North America about 1.8 million years ago, but their earliest recorded appearance in the Park is 1.4 million years ago (McDaniel and Jefferson, in press).
— Fossil Treasures, Mammoths and Their Relatives, Introduction

Are there mammoths in southern California?
Yes. Mammoths are well documented in southern California, particularly within Anza-Borrego Desert State Park, where more than 80 proboscidean fossil localities have been recorded. These include mammoths of the genus Mammuthus that lived in the region from approximately 1.4 million years ago through the late Pleistocene.

How many mammoth sites are known in Anza-Borrego Desert State Park?
​More than 80 fossil localities yielding proboscidean remains have been documented within Anza-Borrego Desert State Park, making it one of the most productive proboscidean fossil regions in North America.
