Three geographically isolated populations are known to exist. These populations have been shown to be genetically distinct. For most of the year, males and females live apart from each other. The females live on the better part of the rocky slopes, while the males live on the margins, usually lower on the mountain. In order to breed, the males migrate to the females' habitat. During the ski season on Mount Higginbotham, the males had to cross a road which put their survival in jeopardy. A "Tunnel of Love" was constructed under the road and a road sign was put in place to warn drivers.
