Short summary
This study explores how rocks on glacier surfaces originating from rockfalls help measure erosion rates using a chemical marker called 10Be. By analyzing data from 31 glaciers we found that erosion rates vary widely but can be accurately estimated and reveal links to rock exposure, glacier movement, and climate effects. Comparing 10Be erosion rates to other exhumation rates shows cases of balance, slower erosion, or faster erosion, offering insights into the complex drivers of rockwall erosion.
