In the desert of southeastern California, the geological and archaeological remnants of a once massive lake, Lake Cahuilla, are still visible. One of the most distinctive features marking Lake Cahuilla's relic shorelines is a series of rock fish trap features that, in some cases, stretch across thousands of square meters. These fish traps are severely understudied, and systematic archaeological survey can help scientists reconstruct the dynamic human-environmental history of the region. The large number of fish traps along with the rocky desert terrain, however, make traditional pedestrian archaeological surveys both difficult and inefficient. We used unmanned aerial vehicle (UAV) technology along with traditional archaeological methods to conduct surveys and identify patterning in the shapes, orientations, and frequencies of fish traps. Our study demonstrates the potential of emerging archaeological field technology to better understand the nature of human-environmental ecodynamics through time and space.

沙漠中的海岸线：绘制加利福尼亚州卡威拉古湖西南海岸的捕鱼器特征

在加利福尼亚州东南部的沙漠中，曾经巨大的卡维拉湖的地质和考古遗迹仍然可见。标志着卡威拉湖遗迹海岸线的最显着特征之一是一系列岩鱼陷阱特征，在某些情况下，这些特征延伸到数千平方米。这些捕鱼器的研究严重不足，系统的考古调查可以帮助科学家重建该地区动态的人类环境历史。然而，大量的鱼类陷阱以及多岩石的沙漠地形使传统的行人考古调查既困难又低效。我们使用无人驾驶飞行器 (UAV) 技术以及传统的考古方法来进行调查，并确定捕捞器的形状、方向和频率的模式。
