The cover picture shows two powder X‐ray diffractograms recorded from two different "ice" samples obtained by pressurizing cubic (red) and hexagonal (black) ice crystals at ≈80 K. Sharp peaks marked with an asterisk are from traces of hexagonal ice. In their Communication on page 1203 Loerting et al. demonstrate that the two types of ice I obtainable at ambient pressure result in two different structural states of high density amorphous ice (HDA) when pressurized to 1.5 GPa at 77 K. The background image is a high‐resolution photograph of a hexagonal snowflake provided by Professor Kenneth G. Libbrecht (California Institute of Technology).
