Features which have been interpreted as "fire hearths" and "charcoal" have been recorded in association with mammoth and other Pleistocene faunal remains. Some of these remains have been dated by the radiocarbon method as exceeding 10,000 years; a few are considerably in excess of this time. A review of some of these remains suggests the probability of noncultural origin for the carbonaceous material in question. Recent excavations in Merced and Orange counties, California, have revealed Pleistocene faunal remains in direct association with an abundance of carbonaceous material. It can be demonstrated that these remains are noncultural in origin.
