In just one place in the United States do four states meet. The borders of Utah, Colorado, New Mexico, and Arizona intersect at Four Corners, west of the confluence of the Mancos and San Juan Rivers. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured this image of the region on June 11, 2011. ASTER produces images using infrared, red, and green wavelengths of light. Vegetation is red, and sparsely vegetated or bare areas range from off-white to gray to tan. Water appears navy blue to nearly black. Vegetation (bright red) lines the braided river channels, but the rarity of red in this image attests to the general paucity of vegetation in the region, where shrubs dot plateaus and dry valleys.
