While hiking the Hoodoo Trail, I turned to a view point above the Milk River on top of the steep cliffs above. I stopped suddenly when I heard native singing, resonating beautifully between the sandstone crevices. Not wanting to disturb the prayers, I stood silently, entranced. Eventually I retreated and continued out to the Battle Scene rock art depiction, one of the highlights of this World Heritage Site in Alberta Canada.

Later I took the guided tour of the restricted area where Blair showed and explained the rock art in this spiritual place of the Blackfoot Tribe. The tour started at 5 pm, perhaps to take advantage of the light as well as coolness. While I disagree with those who look for extraterrestrial interpretations of some of the unusual petroglyphs and pictographs, the details and 2500 years represented here are intriguing and fascinating. Still, for me, I will never forget the living voice I heard echoing among the hoodoos.
