a Convergence of Wonders in the Pacific Northwest and Northern Rocky Mountains, dawned bright and clear as we set out on the long road home, still three more days away. The day began with an absolutely stunning view of the crest of the Grand Tetons, which just begged for a panorama shot on my wife's camera (click on the photo above for the full effect). These peaks are composed of exceedingly ancient metamorphic rocks of the deep crust that have been lifted miles into the sky. The valley floor on which we stood contained thousands of feet of sediment washed from the mountains. The faults responsible for these incredible mountains are undoubtedly still active, which brings us to the theme of the day, if there is any such thing, the idea of geologic hazards. Another thing I sort of realized on reflection was the hidden nature of some of the geology we would be seeing today. We were leaving the really famous national parks behind, and exploring some lesser known parts of the American West.
Game Creek Archaeological Dig. A highway widening project had uncovered artifacts, and a multi-year excavation revealed a stratified site that encompassed some 10,000 years of human occupation at this location.
