In his Snowballs in Summer series, Goldsworthy makes large snowballs in winter and preserves them until the summer. Inside of each snowball, he “hides” different materials such as chalk, old pine needles, and dogwood [pictured above]. For this project, Goldsworthy is interested in how different snow melts, the patterns the materials inside will melt into, and the relationship between a city and the imposed natural form.
