Salar de Uyuni (or Salar de Tunupa) is the world's largest salt flat at 10,582 square kilometers (4,086 sq mi). It is located in the Potosí and Oruro departments in southwest Bolivia, near the crest of the Andes, and is elevated 3,656 meters (11,995 ft) above mean sea level. The Salar was formed as a result of transformations between several prehistoric lakes. It is covered by a few meters of salt crust, which has an extraordinary flatness with the average altitude variations within one meter over the entire area of the Salar.

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.

Potoos (family Nyctibiidae) are a group of near passerine birds related to the nightjars and frogmouths. They are sometimes called Poor-me-ones, after their haunting calls. There are seven species in one genus, Nyctibius, in tropical Central and South America.
These are nocturnal insectivores which lack the bristles around the mouth found in the true nightjars. They hunt from a perch like a shrike or flycatcher. During the day they perch upright on tree stumps, camouflaged to look like part of the stump. The single spotted egg is laid directly on the top of a stump.

Andy Kehoe recently returned to New York for his third solo show with Jonathan LeVine Gallery. Entitled Luminous Reverie, this show explores the idea of experiencing a lucid moment while drifting along in a daydream. We enjoyed the works, which continued the new direction that he premiered during a show in Los Angeles last year (covered). Again, Kehoe explores the technique of painting layers upon layers of resin and creating a natural 3-D visual element for the viewers to enjoy. This show will be up until June 15th, so stop by and check it out if you’re in NYC.

Though we have “In God we trust” written on our banknotes, we didn’t go as far as putting Jesus on them. Martin Joubert, however, decided to correct this injustice and placed the face of Jesus on one of his 100 dollar designs. Though some may view it as sacrilege, Jesus surely wouldn’t mind seeing his face on the banknote of one of the most pious nations in the world. In our opinion, however, the monopoly man is the most appropriate substitute for the Ben Franklin. (Photo by Martin Joubert)
