Jacob's Well is a perennial karstic spring in the Texas Hill Country flowing from the bed of Cypress Creek, located northwest of Wimberley, Texas. The twelve foot (four meter) diameter mouth of the spring serves as a popular swimming spot for the local land owners whose properties adjoin Cypress Creek. From the opening in the creek bed, Jacob's Well cave descends vertically for about thirty feet (ten meters), then continues downward at an angle through a series of silted chambers separated by narrow restrictions, finally reaching a depth of one hundred and twenty feet (forty meters). Until the modern era, the Trinity Aquifer-fed natural artesian spring gushed water from the mouth of the cave, with a measured flow in 1924 of one hundred and seventy gallons per second (six hundred and forty liters per second) discharging six feet (two meters) into the air. The spring is the greatest source of water recharging the Edwards Aquifer.

“Actor and director Mel Gibson has pleaded no contest to a “misdemeanour” battery charge after a fight with then-girlfriend Oksana Grigorieva in 2010. Gibson, 55, was placed on probation for 36 months and ordered to attend a year of domestic violence counselling. The complaint accuses Gibson of “wilfully and unlawfully” using force and violence against Ms Grigorieva. A misdemeanour charge is generally considered a lesser criminal act than a felony charge in the US”. – BBC News
