Resumen:
Northern Chilean Patagonia has numerous pristine lakes associated with Nothofagus and Araucaria araucana forests. The present study consists of a study of optical properties in visible, close, and medium infrared wavelengths in mountain lakes surrounding Llaima Volcano lakes that have associated Nothofagus and Araucaria araucana native forests with volcanic origins. The results revealed high reflectance values in Arcoiris Lagoon that has volcanic stones in its bottom, whereas the other lakes and lagoons have low reflectance values. These differences in spite of oligotrophy would be associated with surrounding vegetation and geological characteristics of studied sites.
