Under the guidance of Dr. David Browman, Mr. Cristobal Gnecco, a graduate student at Washington University will collect data for his doctoral dissertation. In 1985, an extensive archaeological site was discovered in the course of road and sewer construction in the Popayan Valley in southwestern Colombia. Preliminary analysis indicates that the stone tools are attributable to paleoindian hunters and gatherers and may date to approximately 11,000 years ago. With NSF support, Mr. Gnecco will return to the La Elvira site and conduct careful stratigraphic excavation. He will strip a large horizontal expanse both to recover additional cultural materials and to set the site into a clearer geological context. Distributional data thus collected will hopefully shed light on the spatial organization of activities. Both organic and obsidian materials will be dated by radiocarbon and hydration techniques respectively. Finally, Mr. Gnecco and his collaborators will attempt a paleoclimatic reconstruction of the site. A core will be obtained and pollen and plant macrofossils analyzed. Regional vegetation will be collected to provide a comparative base. Although archaeologists agree that the first people to enter the New World crossed from Asia via the Bering Land bridge into Alaska, it has been surprising to learn that some of the earliest known archaeological sites are located in South America. Just how and when the first peoples entered this part of the world is unknown. It is also surprising that while in North America these "paleoindian" peoples are associated with big game hunting in relatively open environments, in South America such appears not to be the case. The question of paleoindian prehistory in South America is complicated by the relative dearth of archaeological data. In this context, information recovered from the La Elvira site is extremely important. It is also interesting that this rich archaeological occurrence is located in a forested valley. This research is important for several reasons. It will help to fill a glaring archaeological gap and the data will be of great interest to a large number of prehistorians. The research should shed new light on the adaptations of early New World peoples and will help in the training of an extremely promising young scientist.

在大卫·布朗曼博士的指导下， 华盛顿大学的一名研究生将收集数据， 他的博士论文。 1985年，一场大规模的考古 在修建道路和下水道的过程中发现了一个地点 位于哥伦比亚西南部的波帕扬山谷。 初步 分析表明，这些石器可归因于 古印第安猎人和采集者，可以追溯到大约 一万一千年前。 在NSF的支持下，Gnecco先生将回到 并进行仔细的地层挖掘。 他将剥离一大片水平区域， 更多的文化材料，并设置为一个更清晰的网站 地质背景。 收集的分布数据将 希望能揭示活动的空间组织。 有机物和黑曜石物质都将通过放射性碳测定年代 和水化技术。 最后，格尼科先生和 他的合作者们将尝试重建 本网站 一个核心将获得花粉和植物 宏化石分析 将收集区域植被， 提供一个比较基础。 尽管考古学家认为第一批进入 新大陆从亚洲通过白令陆桥进入 在阿拉斯加，令人惊讶的是，一些最早的 已知的考古遗址位于南美洲。 只是 第一批人是如何以及何时进入这一地区的， 未知 同样令人惊讶的是，在北美， “古印第安人”与大型狩猎有关， 在相对开放的环境中，在南美洲， 这是事实。 南方古印第安人史前问题 美国由于考古学的相对缺乏而变得复杂 数据 在这方面，从La Elvira号上获得的信息 网站非常重要。 同样有趣的是， 丰富的考古发现位于森林山谷。 这项研究之所以重要，有几个原因。 这将有助于 填补了考古学上的空白， 引起了大量史前学家的兴趣。 这一研究应 对早期新世界人民的适应性有了新的认识， 将有助于培养一个非常有前途的年轻人 科学家
