A section of the Hardrock Trail at Empire Mine State Historic Park, between Stacey Lane Trail and the Sand Dam spillway, is closed until further notice due to the rapid development of a sinkhole.
The closed trail section is extremely unstable, and any area within the closed section may be vulnerable to collapse without warning. Park visitors, hikers and equestrians are strongly advised to utilize the trail bypass, along the main Stacey Lane Trail and the Stacey Lane Crosscut Trail, which safely circumvents the area.
The length of affected trail within the closed area, and the sinkhole stabilization timeframe, is not currently known. Park staff and geologic consultants are currently assessing the situation and a reopening date will be announced when determined.
