Snow blankets the higher terrain at the heart of the 130,000 square-mile Colorado Plateau in this image captured by NASA’s Terra satellite yesterday.

Left behind by the same storm system that’s now hammering the East Coast, the snow frames the deeply incised canyonlands of the Colorado River and its tributaries, which runs diagonally across the image. At lower left, where the river makes a big bend, you can spot the Grand Canyon. It bisects the Kaibab Plateau (part of the bigger Colorado Plateau), which reaches an elevation 9,241 feet above sea level. The darker, greenish coloring that edges the snow-covered area is indicative of forests that grow on this higher ground.

Also visible in the image is Lake Powell, the reservoir on the Colorado River that serves as a massive hydrologic savings bank for some 30 million people in seven states and Mexico who depend on water from the river and its tributaries. The snow is a good sign for a region plagued by drought for more than 10 years.

And with that let me wish everyone a very happy Thanksgiving!

    Makes you wonder, if we hadn’t deforested the Rockies for short-term profits would all these storms drop their payloads on the West Coast instead of Eastern seaboard eliminating the frequent droughts they suffer?

    Sorry, using science to correct unbridled capitalism again, I know it is heresy.

      Nope.

      A) The rockies haven’t been deforested, at least not compared to the UK or most of lowland Europe. There are few dense forests in this image because the region is a desert.

      B) Precipitation is controlled by atmospheric conditions which are influenced to some degree by topography, not by vegetation

      C) The region suffers frequent droughts (and has for millions of years) because most moisture coming from the Pacific falls as the wet air masses push up over the Sierra Nevada

      I doubt our economic system has any influence on the precipitation. Where the moisture goes after it hits the ground, though, is a different question.

        The Rockies were deforested 100-200 years ago along with the Sierra Madres. Try history, it works!

        The “water cycle” is partly formed by forestation capturing water vapor. You can wiki it or GOOGLE IT.
