五头乳齿象、三头冰河期野牛和一头幼年哥伦比亚猛犸象的部分遗骸，以及植物和昆虫都已被发现。
Partial remains of five mastodons, three Ice Age bison and a juvenile Columbian mammoth, as well as plant matter and insects, have been found.
而体型较大的哥伦比亚猛犸则生活在较远的南方。

哥伦比亚猛犸与今天的大象有着亲缘关系。他们在一万年以前的大冰河时代结束之时就已灭绝。
Columbian mammoths are ancient Cousins of the modern elephant, and they have been extinct since the end of the last Ice Age more than 10,000 years ago.
“由于长毛猛犸和哥伦比亚猛犸的生活区域会发生周期性的重叠，所以它们可能具有相似的生活习惯和相似的遗传标记。”Enk说。
"Since woolly and Columbian ranges periodically overlapped in time and space, it's likely that they engaged in similar behaviour and left a similar genetic signal, " Enk said.
但是，考古学家表示，很多此前发现的猛犸象骨骼化石中含有史前洪水冲击下来的碎片。冰河时代末期的哥伦比亚盆地曾屡次受到史前大洪水的冲击。
But most prior discoveries of mammoth bones have involved fragments washed down during the prehistoric floods that repeatedly swept across the Columbia Basin at the end of the Ice Age.
