Physiographic attributes of the study area. (a) Location of the study area (red rectangle) on the southwestern peninsula of Sulawesi. Yellow circles show marine sediment cores used for sea-surface temperature reconstructions discussed in this study. (b) Physiography of the Maros-Pangkep karst and locations of rock art sites specific to this study (blue circles). Yellow square shows Gempa Bumi Cave with a speleothem δ18O reconstruction of local rainfall. (c) Exfoliation of cave surfaces (pale areas) and damage to Pleistocene paintings of pigs in the Leang Tedongnge rock shelter. Base maps were created by A. K. Kimbrough in QGIS 3.20 (https://qgis.org/en/site/) and Adobe Illustrator CC using Shuttle Radar Topography Mission 1 Arc-Second Global by NASA/NGS/USGS (2015-01-01 EPSG4326_31m).
