Fig. 2

A Overview of Juneau Icefield; glacier extent in 2019 is shown in red. Key glacier names are shown. Glaciers in black not included in the study area. Overlain on background of ASTER GDEM. B Field photograph (credit Bethan Davies) of Mendenhall Glacier, in June 2022. C Examples of aerial imagery used in glacier reconstruction (1948) for Mendenhall Glacier and Lemon Creek Glacier. Image courtesy of the U.S. Geological Survey. D Example of satellite imagery (Sentinel-2A, 2019) for Thiel Glacier (north-flowing) and Eagle Glacier (south-flowing). E Example of reconstructed glacier area loss for Mendenhall Glacier and Lemon Creek Glacier. Historical glacier positions from ref. 28. C, E have the same scale and extent. Extents are shown in (A).
