Study: Loss of water in drought caused Sierra Nevada to rise

Loss of water from rocks during drought caused California's Sierra Nevada to rise nearly an inch (2.5 centimeters) in height from October 2011 to October 2015, according to a new NASA study made public Wednesday.

The study also found that in the following two years of increased snow and rain, the rocks in the range regained about half as much water as was lost during the drought and the return of the weight caused the height of the mountains to fall about half an inch (1.3 centimeters).

"This suggests that the solid Earth has a greater capacity to store water than previously thought," study leader Donald Argus of NASA's Jet Propulsion Laboratory in Pasadena,...
