The Dawn Settlement near Dresden in southwestern Ontario was a mid-19th-century community of escaped slaves, or “freedom seekers,” from the United States. In this study, a multicomponent geophysical survey (ground-penetrating radar, magnetic gradiometry, and electrical resistivity) was conducted on the British American Institute Cemetery, one of the two cemeteries directly associated with the settlement, to document the location of freedom-seeker graves whose markers had been damaged, knocked over, or removed during the 1960s due to the neglect and forgotten history of these burials. All the techniques provided useful information contributing to site interpretations, although GPR was found to be the most useful in identifying possible graves. We discuss the significance of incorporating archaeogeophysics techniques into heritage-management strategies and our responsibility to protect historical black cemeteries. Our survey also represents one of the first cemetery investigations related to the Underground Railroad in Canada.

黎明定居点被遗忘的灵魂：对英美公墓无标记坟墓的多组分地球物理调查

安大略省西南部德累斯顿附近的黎明定居点是 19 世纪中叶的一个来自美国的逃亡奴隶或“寻求自由者”的社区。在这项研究中，对英美公墓（与定居点直接相关的两个墓地之一）进行了多分量地球物理调查（探地雷达、磁梯度测量和电阻率），以记录寻求自由者坟墓的位置由于这些墓葬的疏忽和被遗忘的历史，它们的标记在 1960 年代被损坏、撞倒或移除。所有技术都提供了有助于解释遗址的有用信息，尽管 GPR 被发现在识别可能的坟墓方面最有用。我们讨论了将考古地球物理学技术纳入遗产管理策略的重要性以及我们保护历史悠久的黑人墓地的责任。我们的调查也是与加拿大地下铁路相关的首批墓地调查之一。
