 The Occurrence This mastodon site is a gypsum sinkhole, which appears
to have been infilled during the early Wisconsinan (approximately 70,000 to 80,000 years
ago). Preliminary evaluation of the stratigraphy of the site indicates an environment
first dominated by a fast flowing stream, followed by period of quiescence indicated by
about 30 cm of dark grey clay and peat buildup. This was then followed by a second phase
of fast flowing water, illustrated by an 8 cm pebble unit.These are in turn covered by a thick (about 2 metre) sequence of alternating thick and thin clays, with abundant peat and occasional pebbles. Scattered throughout are many logs, branches and occasional full trees. Some of the wood has been partly replaced by minerals. One bed of interest was encountered, located throughout most of the site about 10cm below the bone horizon. This is a sandy ash unit containing about 20% charcoal fragments. All bones except those directly beneath the skull material have been located above this ash bed.
