The West Desert Trails are unmaintained trails located on approximately 1,830 acres of open space adjacent to the Sierrita Mine in Green Valley, Arizona. This property was purchased by Freeport-McMoRan Sierrita Inc. in 2012. In 2014, Sierrita completed the installation of groundwater extraction wells and related infrastructure in accordance with the sulfate mitigation effort.
Access to the property is only allowed through existing gates and trails. The land is intended to be managed for conservation purposes with the caveat that Sierrita maintains the ability to conduct mitigation operations.
