Kofa National Wildlife Refuge is located in southwestern Arizona between the city of Yuma and the town of Quartzsite in La Paz and Yuma counties. The Corps of Engineers is investigating and monitoring this area through the Formerly Used Defense Sites, or FUDS Program, for munitions and explosive hazards that may remain from previous military activity. This page provides information on McPherson Pass Practice Landmine Area, which is part of the Kofa National Wildlife Refuge FUDS.
The McPherson Pass Practice Landmine Area project comprises 1,295 acres and is located in the southwestern portion of the Kofa National Wildlife Refuge FUDS. The project was used for bivouac-related training in which temporary encampments were set up in unsheltered areas. Antitank mines were used during these activities. Previous inspections have uncovered only one finding of these munitions at the project area.
Today, the property is managed by the U.S. Fish & Wildlife Service as the Kofa National Wildlife Refuge. According to the U.S. Fish & Wildlife Service website, more than 80 percent of the Kofa National Wildlife Refuge is designated as wilderness. It offers visitors the opportunity to enjoy wildlife watching, photography, hiking, camping and limited hunting.
Based on available information, the Corps of Engineers has determined that additional investigations may be required for the McPherson Pass Practice Landmine Area project. Because the area is designated as a wildlife refuge, it may be some time before the Corps of Engineers and the U. S. Fish and Wildlife Service determine the best course of action. Until then, the Corps of Engineers recommends that visitors follow the 3Rs of Explosives Safety (Recognize, Retreat, Report) if they may have encountered a munition.
As part of a Notification and Safety Education initiative for the FUDS Program, the Army Corps of Engineers mailed postcards to landowners within the project area. The goal of the initiative is to raise awareness of the potential risks and hazards associated with FUDS properties and to reduce impacts to human health, safety and the environment until further response activities are initiated at the sites.
