X-ray tomography data of columnar joints in starch

Columnar jointing is best-known from formations in cooled lava, such as the Giant's Causeway, Devil's Postpile, or Fingal's Cave. However, these crack patterns also arise in other systems, most notably in dried starch. The data published here underlies research into the dynamical ordering of columnar joints, and the process by which they select their size or scale (Goehring and Morris, 2005; Goehring, Morris and Lin, 2006).
