‘The sunbathed clay pit’

This painting by John Weeks depicts a Christchurch clay pit at the base of the Port Hills. The pit supplied local brickworks, and its clay was derived from fine-grained, wind-blown silt known as loess. The darker patch in the cliff face contains layers of soil that built up when the loess was not being deposited. When the loess-bearing winds returned, the layers were covered over.
