This image, acquired with the MODIS (Moderate Resolution Imaging Spectroradiometer) on NASA's Terra satellite, provides a wide view of meager western snow cover on January 15. On that day, measurements derived from satellite observations showed that snow blanketed 142,700 square miles (369,700 square kilometers) of the west. That's the lowest coverage for that date in the MODIS record dating back to 2001 and less than one-third of the median. Coverage had increased slightly by January 26.

PORCUPINES ARE WALKING PINCUSHIONS. Their permanently unkempt hairdo is actually a protective fortress of some 30,000 quills. But their body armor can be a liability, too - porcupines are known to accidentally quill themselves. "They're big and dopey and slow," said Tim Bean, an ecologist at California Polytechnic State University who has collared porcupines as part of his research. They waddle from tree to tree, usually at night, to snack on foliage or the nutrient-rich inner layer of bark.
