The National Park Service is unveiling the Trail of Time "interpretive walking timeline trail that focuses on Grand Canyon vistas and rocks to guide visitors to ponder, explore, and understand the magnitude of geologic time and the stories encoded by Grand Canyon rock layers and landscapes." There is a concurrent 3-day symposium on "New Approaches to Geoscience Education in the National Park System" that started yesterday and ties in with Earth Science Week nationwide.
In addition to the actual scaled trail along the rim of the canyon, there are interpretive displays and web resources.
I had planned on participating in all this but we have auditors in all week as a result of our large DOE geothermal data grant. Since we have one of the two largest awards and 45 subcontractors we are one of the first awards to be reviewed. You can guess where I'd rather be.
