Leleiwi Pali from Halemau'u Trail

Leleiwi Pali, or "Bone Altar Cliff", was formed as erosional forces carved out the top of the mountain. A phenomenon known as the Spector of the Brocken is most frequently observed from Leleiwi Pali. The Spector of the Brocken is the viewer's projected image cast upon the clouds and surrounded by an arcing rainbow. In order to view the Spector of the Brocken, conditions must be just right. Late afternoon sunlight and a cloud-filled "crater" may produce this ghostly phenomenon.
