From today's featured article Hoodoo Mountain is a potentially active stratovolcano in the Northern Interior of British Columbia, Canada. Its flat-topped summit is covered by an ice cap that is more than 100 metres (330 feet) thick and at least 3 kilometres (2 miles) in diameter, and has an elevation of 1,850 metres (6,070 feet). The primary rock types comprising the volcano are phonolite and trachyte, which were deposited during six periods of eruptive activity beginning about 85,000 years ago. There was at least one period of explosive activity. The latest eruptive period began around 10,000 years ago. A lava flow covering the southwestern slope may have been produced within the last few hundred years. There have been periods of seismic activity since at least the mid-1980s, indicating possible future eruptions. Two valley glaciers on the sides of the mountain have retreated significantly over the last hundred years. The closest communities are more than 30 kilometres (20 miles) away. (Full article...)

Berlin Modernism Housing Estates is a World Heritage Site designated in 2008, comprising six subsidized-housing estates in Berlin, Germany. Dating mainly from the years of the Weimar Republic (1919–1933), when the city of Berlin was particularly progressive socially, politically and culturally, these buildings contributed to improving housing and living conditions for people with low incomes through innovative approaches to architecture and urban planning. This photograph is an aerial view of the Hufeisensiedlung (Horseshoe Estate), designed by the architect Bruno Taut and built in the late 1920s. Photograph credit: Alexander Savin
