Resumen
Several regions of tropical America show imprints of past glacial activity. These relict landforms
can support the understanding of past climate conditions, such as during the Last Glacial
Maximum (LGM), and the implications that these paleoclimatic conditions could have had on
landscape change. Here, we present and analyze glacial morphologies for the Chirripó
National Park in Costa Rica based on aerial imagery (1:25,000), detailed Digital Elevation
Models, geomorphic mapping, as well as geomorphic assessments in the field to determine
and validate landforms. This study adds valuable insights into the reconstruction of the
maximum expansion of tropical glaciation during the LGM in Costa Rica and into tropical
America glacial landscapes in general.
