Chillahuita dome, located in northern Chile, is a dacite dome possibly associated with the Altiplano-Puna Volcanic Complex.
"Pixellation" of the model is due to the small size of the feature (only a few kilometers across) compared to the resolution of the digital elevation model (30 m/pixel).
Model generated using the ASTER Global Digital Elevation Model from http://gdex.cr.usgs.gov/gdex. 3x vertical exaggeration.
