This image of a young bareback rider was taken in the village of Palenque de San Basilio, in Colombia’s Bolívar department. Founded by freed slaves in the 17th century, it became the first free town in the Americas, following a decree by the Spanish crown. Most of today’s inhabitants are direct descendants of those slaves and have preserved many of their customs, including their own language, Palenquero.

Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO3. In its (rare) pure form, it is typically a rose-red color, but impure specimens can be shades of pink to pale brown. It streaks white, and its Mohs hardness varies between 3.5 and 4. Its specific gravity is between 3.5 and 3.7. It crystallizes in the trigonal system, and cleaves with rhombohedral carbonate cleavage in three directions.

The materialisation of this house is a dream come true for the owner. This house was built in Germany, in the town called Zell and what is the most astonishing about it is the stone used in the whole design. It was built by Walter Andre and it looks as if it just got out from a fairytale, and everything from its fantastic roof to it’s sandstone windows points in that direction.

Fann Mountains are part of the western Pamir-Alay mountain system and are located in Tajikistan's Sughd Province between the Zarafshan Range to the north and the Gissar Range to the south (see map of Fann Mountains). In the east-west direction they extend from Fandarya River to Archimaydan River, and the cluster of Marguzor lakes west of Archimaydan is also included in the Fanns.

When Colin Garratt went to photograph the traditional sentinels of the British countryside, he found they ranged from the dapper to the downright sinister. “They are not from the anaesthetised world of the craft fair”, says Colin Garratt, “but are the direct descendants of the ancient spectres which have haunted the landscape for centuries”. The Scarecrow Exhibition is at Geddes Gallery, London, from 25 to 30 March. (Photo by Colin Garratt)
