We use cosmogenic 26Al/10Be ratios in rocks from the Shackleton Range, Antarctica to investigate geological scatter, a challenge that faces exposure-age studies in Antarctica. Examining the scatter helps reveal the long-term lowering of Slessor Glacier, an outlet glacier of the East Antarctic Ice Sh...
