Utility Trench Monitoring along the West and North Walls, Fort Union Trading Post National Historic Site, North Dakota

The park plans to upgrade its telephone and alarm system. Trenching along the palisade was required to lay the new utility lines. Archeological monitoring was required since portions of this area were believed not to have been disturbed by previous excavation activity associated with the fort reconstruction work from 1986-1989.

该公园计划升级其电话与警报系统。为铺设新的公用设施管线，需沿栅栏开挖沟槽。鉴于该区域部分地块被认为未受1986-1989年堡垒重建工程相关的既往发掘活动扰动，因此需开展考古监测工作。
