The Beulé Gate is a fortified gate leading to the Propylaia of the Acropolis of Athens, Greece. It was constructed largely of repurposed material taken from the 4th-century BCE Choragic Monument of Nikias and integrated into the Post-Herulian Wall, a late Roman fortification built around the Acropolis in the years following the city's sack by the Germanic Heruli people in 267 or early 268 CE. Its construction marked the beginning of a new phase in the Acropolis's use, in which it came to be seen more as a defensive position than a religious sanctuary. During the medieval period, the gate was further fortified, before being built over with a bastion in Ottoman times. The monument was discovered by the French archaeologist Charles Ernest Beulé on 29 May 1852, and excavated in 1852 and 1853. Archaeologists and Greek commentators criticised the aggressive excavation – particularly the use of explosives. In modern times, the gate has served primarily as an exit for tourists from the Acropolis. (Full article...)
Lake Estancia was a prehistoric body of water in the Estancia Valley, in the center of the U.S. state of New Mexico. Mostly fed by creek and groundwater from the Manzano Mountains, the lake had diverse fauna, including cutthroat trout. It appears to have formed when a river system broke up. It reached a maximum water level (highstand) presumably during the Illinoian glaciation and subsequently fluctuated between a desiccated basin and fuller stages. Wind-driven erosion has excavated depressions in the former lakebed that are in part filled with playas (dry lake beds). The lake was one of several pluvial lakes in southwestern North America that developed during the late Pleistocene. Their formation has been variously attributed to decreased temperatures during the ice age and increased precipitation; a shutdown of the thermohaline circulation and the Laurentide Ice Sheet altered atmospheric circulation patterns and increased precipitation in the region. The lake has yielded a good paleoclimatic record. This map shows the shoreline of Lake Estancia at three different periods: early Estancia (1,939 m / 6,362 ft above sea level), late Estancia (1,897 m / 6,224 ft), and "Lake Willard" (1,870 m / 6,135 ft). Present-day populated places, county boundaries and roads are overlaid on the map for identification.
A series of explosions at a depot storing 1,500 tonnes of obsolete munitions forces the evacuation of some 2,000 people in Sofia and the closure of the Bulgarian capital's main airport.
