Short summary
Channels on glaciers are important due to their role in transporting glacial meltwater into downstream river catchments. These channels have received little research in mountain environments. We manually mapped <2000 channels to determine their distribution and characteristics across 285 glaciers in Switzerland. We find that channels are mostly commonly found on low-elevation glaciers with gentle slopes and few crevasses. Most channels run off the glacier, but 20 % enter the glacier.
