series of text on The History of the Study of Landforms. Two further volumes were published in 1973 and 1991. At the time of Chorley's death, Volume 4 was nearing completion. Progress in Geography Instead of confining himself to physical geography, Chorley took a broad approach to change in geography as a whole. He did this first through a series of annual summer conferences held at Madingley Hall near Cambridge, where his lectures helped form a basis of a series of volumes (notably Models in Geography, 1967) that influenced the discipline. The second was by founding an annual series, "Progress in Geography", later converted into two influential quarterly journals, in which changes over the whole discipline could be recorded and assessed.
