Exposure of a partial mammoth skeleton in an arroyo bank above the high water level of Lake Mead prompted initial field visitation. A 1987 visit resulted in a recovery of limb elements in the arroyo wall, and a maxillary tooth below the existing lake level. Continued monitoring of the site, by NPS personnel, revealed tusk, rib and long bone fragments in sediments below the high water level. A NPS request led to field visitation and salvage excavation during the fall of 1991. The specimen was originally preserved in alluvial deposits grading from the Muddy Mountains to the Virgin River arm of the reservoir. Examination of the deposits led to the conclusion the faunal material below lake level was the result of arroyo wall collapse and reworking of the material by high lake level. This specimen represents the first reported Mammuthuscolumbi remains from this portion of Clark County, Nevada.
