EXCAVATION OF MAMMOTH
This picture was taken in 1981 and it
shows three excavators working in the main bone bed area on the
Lange Ferguson site. The excavation of this site began in 1980 and
continued into 1984. Bone beds are the most difficult to excavate.
One problem is the organic bone material begins to deteriorate when
exposed to the air. The bones require special chemical treatment to
preserve them. The larger specimens are encased in plaster jackets.
They also need special handling for transport to a storage facility.
