Andy Goldsworthy's Wood Line installation along Lovers' Lane in the Presidio of San Francisco, California, USA

Winding through nature

This sinewy trail was created by the British environmental artist Andy Goldsworthy, who is known for his work with natural materials like leaves, sand, ice and stone. This particular work, Wood Line, is in the Presidio park in San Francisco, USA and uses felled eucalyptus trees which are intended to biodegrade and eventually fade back into the forest floor. It sits at the south end of Lovers’ Lane, the oldest footpath through the park, which was established in the 18th century as a short cut used by Spanish soldiers and missionaries. More than 1,200ft (365m) long, Wood Line is one of four pieces by Goldsworthy in Presidio, a national park that once served as a US military outpost.
