The summer drought of 2007 allowed scientists and archaeologists in Florida to look through a window into the state's past and uncover hidden treasures just below the surface of Lake Okeechobee.

Okeechobee is the nation's second largest lake. Because of the drought, the lake hit its lowest level on record. In some areas the shoreline receded more than a mile, creating areas of dry lakebed where historical artifacts have been uncovered, with some dating back 500 years or more.

Pottery shards, arrowheads, weaving tools, and pendants now lay on top of the dry ground, providing clues about the Native Americans that lived in the area hundreds of years ago. Evidence of the Florida tourism and fishing industries also lurk nearby, including a fishing trawler from 1904 that probably sank during a hurricane in 1928 and evidence of paddleboats that once ferried tourists around the area.

All these items have rested just beneath the surface of the water for many years. It took a drought to bring them out into the light of day again.

Spiritual droughts are not fun, to say the least. But the trials and moments of doubt that come during personal drought can reveal many things about us.
