The Decade of the Geology of North America (DNAG) of the Geological Society of America is an effort to recapitulate progress in North American geology. In my talk I will attempt to put in perspective North American Phanerozoic mountain systems, and sedimentary basins as well as the evolution of the Precambrian to illustrate where I think we stand today. This in turn will lead to the future directions of our earth science enterprise.

As we enter the 21st century we will face more advances in the specialized subfields of Geophysics and Geochemistry. All these will have to be integrated into a coherent Earth-System Science to show linkages between all geological processes. Because in Houston, cooperation between geochemists, geophysicists and geologists is already a way of life, members of our societies will be leaders in the integration process.
