Figures must be maintained to remain visible, and local people often work regularly to restore or maintain a local landmark, though two cuttings of military badges at Sutton Mandeville, Wiltshire, are becoming lost. A map of Australia at Compton Chamberlayne, Wiltshire, was lost in 2005. Similar pictures exist elsewhere in the world, notably the far larger Nazca Lines in Peru, which are on flat land but visible from hills in the area. However, these were made in desert terrain rather than on grassy hillsides, so have not become overgrown and thus have survived much longer without maintenance. The Nazca Lines were formed by removing loose stones from the lines to expose the whiteish underlying soil, which is not itself dug. Terminology Geoglyph is the usual term for structures carved into or otherwise made from rock formations. In 1949, Morris Marples "half-humorously" coined the words "leucippotomy for the cutting of white horses and gigantotomy for the cutting of giants on rare occasions". Though neither word appears in the Oxford English Dictionary, the terms occasionally appear in print. Construction Until recently, three methods were used to construct white hill figures. The stripping method: where the soil is thin, the turf or soil is stripped away to expose the chalk underneath. This produces quick results but the figure needs regular maintenance, as it would soon become overgrown. This was a practice for hill figures but not as much for horses. The Laverstock Panda at Laverstock near Salisbury, Wiltshire was constructed this way in 1968 and is now lost. Traces of figures of this type are not usually found after the figure is overgrown. The covering method: rocks are placed on top of the turf. This method is normally used when there is no underlying chalk, the chalk is deep or tools are not available. The maintenance for these figures is very high. There are several examples, such as the Woolbury White Horse in Hampshire. This method leaves no trace of the figure's existence when overgrown, as is the case of the lost Fovant Badges in Wiltshire. The trenching method, which is by far the most common method of hill figure construction. The underlying chalk where some white horses are constructed is not near the surface, so a trench is dug and chalk from another site is used to fill it. The Uffington White Horse in Oxfordshire is the prime example
