See attached pictures showing the damage. This incident at Red Rock compromised a closed sensitive area and certainly does not help our efforts to maintain OHV access to the area, the north end of Nightmare where it transitions out to a gate and eventually leads out into the northwestern portion of Last Chance Canyon and Nightmare Gulch.Red Rock Canyon State Park issued an Emergency Closure of Nightmare Gulch on October 9, 2013. The Emergency Closure was issued as a result of summer storm damage which rendered the canyon impassable to vehicles. While the closure is temporary, before any trail repair can be performed an environmental assessment is required. This whole process could take many months. - See more at: Nightmare Gulch ClosedThis trespass has the unintended consequence of jeopardizing the pending acquisition of Onyx Ranch property in the adjacent Jawbone/Dove Springs area.
