LEWISTON – The Nez Perce Tribe in North Idaho has closed Six Mile Canyon to the public after homemade nail strips and road spikes were found on roads and trails.
The first nail strip was found Tuesday when it flattened a tire on an all-terrain vehicle.
Tribal conservation officials found three more nail strips on Wednesday. They returned on Thursday with the Idaho State Police and found more nail strips and road spikes.
The area is popular with hikers, bird watchers and people riding horses.
An official said the area will remain closed until the person or persons responsible can be identified.
