Crevasse initiation is linked to strain rates that range over three orders of magnitude (0.001 and 0.163 a–1) as a result of the temperature-dependent nonlinear rheological properties of ice and from water and debris inclusions. Here we discuss a small cold glacier that contains buried crevasses at...
