Editorial statement
These data are unique to Greenland, particularly from the base of the Camp Century ice core. These data, which show several periods of glaciation and non-glaciation in northwest Greenland prior to the formation of the current ice cap, should be of great interest to the paleo community, from paleoecologists to modelers.

Short summary
The Camp Century subglacial core stores information about past climates and glacial and interglacial processes in northwestern Greenland. In this study, we investigated the core archive, making large-scale observations using computed tomography (CT) scans and micron-scale observations observing physical and chemical characteristics of individual grains. We find evidence of past ice-free conditions, weathering processes during warmer periods, and past glaciations.
