The La Prele site (ca. 12,940 cal BP) is a deeply buried, single-component mammoth kill and campsite in Wyoming (USA). The site was discovered eroding from a creek bank 3 m deep within a 7-m tall terrace scarp, and prior investigations have primarily focused on excavations accessible from the creek bank, using heavy machinery to remove sterile overburden to access the deeply buried deposits. This approach has allowed excavations to occur safely outside of deep pits, but it has limited our ability to assess the total size and density of the site. To determine total site extent, we conducted systematic bucket auger testing of the La Prele site terrace, attempting 189 augers between 1.6 m and 6.2 m deep across the landform. We use a simulation and other mathematical procedures to infer artifact density from auger artifact counts and interpolate artifact densities across the site using GIS. We determine that La Prele is around 4500 m² in area and likely contains a buried bison bonebed and two additional artifact concentrations comparable to or exceeding the size and density of previously excavated areas. We use these insights to infer Early Paleoindian group size, concluding that around 30 people occupied La Prele.

拉普雷勒遗址（距今约 12,940 卡路里）是位于美国怀俄明州的一处深埋的单一猛犸象猎杀和露营地。该遗址被发现是从 7 米高的台地陡坡内 3 米深的溪岸侵蚀而来，之前的调查主要集中在可从溪岸进行的挖掘，使用重型机械去除无菌覆盖层，以进入深埋的沉积物。这种方法允许在深坑之外安全地进行挖掘，但它限制了我们评估场地总大小和密度的能力。为了确定场地总范围，我们对 La Prele 场地阶地进行了系统的斗式螺旋钻测试，在整个地貌的 1.6 m 至 6.2 m 深之间尝试了 189 个螺旋钻。我们使用模拟和其他数学程序从螺旋钻工件计数推断工件密度，并使用 GIS 插值整个站点的工件密度。我们确定拉普雷莱的面积约为 4500 m ² ，可能包含埋藏的野牛骨床和两个额外的人工制品浓度，其大小和密度相当于或超过先前挖掘区域的大小和密度。我们利用这些见解来推断早期古印第安人群体的规模，得出结论，大约有 30 人居住在拉普雷莱。
