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.

“Body blading (also known as buggy rollin') is an extreme sport that involves descending down a slope while wearing a flexible aerodynamic plastic roller suit that has wheels on the feet, knees, torso, and arms. This suit was created by Jean-Yves Blondeau, and he is one of the premier body bladers. Body blading is similar to roller blading, and in fact a body blader often starts out using the rollers on their feet in the same fashion as roller blades in order to gain initial speed, but then the rider generally assumes a position laying on the stomach facing down the hill. A body blader is capable of reaching very high speeds. Maneuverability is achieved by moving the body into various positions to change direction”. – Wikipedia

Among the fish populations that could be harmed by the Xayaburi dam in Laos is the critically endangered Mekong giant catfish, considered by the Guinness Book of World Records to be the world’s largest freshwater fish. The fish, which grows to 650 pounds and about 10 feet long, is only found in the Mekong River. It is migratory, moving between downstream habitats in Cambodia upstream to northern Thailand and Laos each year to spawn. Some experts fear the Xayaburi dam could block the migration and drive the giant catfish to extinction. (Photo by Courtesy of Zeb Hogan/University of Nevada, Reno)
