摘要

时间、恶劣天气和有限的预算可能会阻碍考古调查工作。在这里,我们通过在鹅湖出口#3(GLO#3)现场(20MQ140)使用探地雷达(GPR)来改进其中的一些。用于指导这些排水良好的沙质土壤中的调查和挖掘工作的探地雷达调查是有限的。GPR图像显示假阳性;然而,铲子探测器、随后的遗址挖掘和人工制品分析在这个原始历史遗址上发现了许多发现,其中包括可追溯到1630年代的玻璃贸易珠。这些发现巩固了该地区一些最早欧洲制造的贸易物品的证据,并进一步证实了苏必利尔湖和密歇根湖之间的印度小径和古代旅游走廊的位置。从具有贸易商品特征的驼鹿骨骼中获得的两个14C样本属于1633–1668和1615–1647的预期职业范围。在探地雷达图像上可以看到一些异常,可能的炉膛集群;然而,许多特征仍然是看不见的。

Ground Penetrating Radar in the Northern Great Lakes
Timing, inclement weather, and limited budgets can obstruct archaeological survey efforts. Here, we ameliorate some of these with use of ground penetrating radar (GPR) at the Goose Lake Outlet #3 (GLO#3) site (20MQ140). GPR surveys to guide survey and excavation efforts in these well-drained sandy soils are limited. GPR imagery exhibited false positives; however, shovel probes, subsequent site excavation, and artifact analysis led to numerous discoveries at this protohistoric site—including glass trade beads dating to the 1630s. These discoveries solidify evidence for some of the earliest European-made trade items in the region and provide further confirmation for placement of an Indian trail and ancient travel corridor between Lake Superior and Lake Michigan. Two 14C samples obtained from moose-bone in features with trade goods fall within the expected occupation range of 1633–1668 and 1615–1647. Several anomolies, possible hearth clusters were seen on the GPR imagery; however, many features remained invisible.
