America Tapestry of Time and Terrain (1:8,000,000 scale) is a product
of the US Geological Survey in the I-map series (I-2781). This map was prepared
in collaboration with the Geological Survey of Canada and the Mexican
Consejo Recursos de Minerales.
Tapestry is woven from a geologic map and a shaded relief image. This
digital combination reveals the geologic history of North America through
the interrelation of rock type, topography and time. Regional surface
processes as well as continent-scale tectonic events are exposed in the
three dimensions of space and the fourth dimension, geologic time. The
large map shows the varying age of bedrock underlying North America, while
four smaller maps show the distribution of four principal types of rock:
sedimentary, volcanic, plutonic and metamorphic.
This map expands the original concept of the 2000 Tapestry of Time and Terrain, by José F. Vigil, Richard J. Pike and David G. Howell, which covered the conterminous United States. The U.S. Tapestry poster and website have been popular in classrooms, homes, and even the Google office building, and we anticipate the North America Tapestry will have a similarly wide appeal, and to a larger audience.
