ABSTRACT
Northern Chilean Patagonia has numerous pristine lakes associated with perennial native forests. The
present study looks at optical properties in visible, close, and medium infrared wavelengths in mountain lakes
of Alerce Andino National Park (41°S). These lakes have associated Nothofagus and Fitzroya cupressoides
native forests of glacial origins. The results revealed high reflectance values for B1 and B3 for Chaiquenes,
Triangulo, and Sargazo lakes located within Nothofagus and F. cupressoides native forest; Precipicio
Lagoon has high B3, B4, B5, B6, and B7 reflectance values, perhaps due to granite surroundings; and the
remaining 18 lagoons have relative low reflectance values for all bands, probably due to the predominance
of Cupressaceae forest and mountains that make access difficult. These differences are associated with
surrounding vegetation and geological characteristics of the studied sites.
