Quite a while back, there were just 35 pupfish included in the water, yet in Spring of this current year, researchers counted 175 fish.

A solid seismic tremor recently in Mexico set off 4-foot-tall waves in Death Valley's Demons Opening.

Estimating 7.6 on the Richter scale, the seismic tremor was focused around 100 miles southeast of Guadalajara.
