Also known as Huntington Canyon
Where: Sanpete County, Utah (39.6° N, 111.3° W: paleocoordinates 39.6° N, 111.2° W)
• coordinate stated in text
• small collection-level geographic resolution
When: Late/Upper Pleistocene (0.1 - 0.0 Ma)
• C14 dates of 11,420 +/- 110 BP "on a fir needle from stomach contents" of the mammoth and 11,220 +/- 110 BP on mammoth bone, plus "bracketing dates of 9,580 +/- 90 BP and 9,440 +/- 60 BP on spruce wood from stratigraphically below and above the mammoth bones" that indicate reburial
• bed-level stratigraphic resolution
Environment/lithology: lacustrine; claystone
Size class: macrofossils
• "nearly complete" mammoth skeleton plus "a cranial fragment" of a bear that apparently were reburied "nearly 2,000 years later" after deglaciation, based on C14 dates
•mammoth bones have apparent ursid gnawing marks, and there is a "series of bifacially-worked lithic tools" that may or may not be of the same age as the fossils
Collected in 1988
