Why the Four Corners Region?

The Four Corners region sits atop one of North America's most geologically diverse and scientifically significant landscapes. Here, the Colorado Plateau reveals over 2 billion years of Earth's history through spectacular exposures of sedimentary, igneous, and metamorphic rocks.

From the oil and gas boom of the 1950s to today's exploration for critical minerals, this region has been at the forefront of geological discovery. Our unique position allows us to study everything from Precambrian basement rocks to Pleistocene glacial terrains, making the Four Corners an ideal laboratory for advancing geological science.

Colorado Plateau

Unique geological province with exceptional preservation of sedimentary sequences

Petroleum Resources

Oil and gas production from multiple Laramide basins utilizing developing technologies

Mining Heritage

Rich history of gold, silver, copper and uranium. Future potential for critical minerals is driving innovation

Tectonic Setting

Unique location for studying structural geology and tectonic influences
