A road leads to a sulfur mine near the summit of 5890-m-high Putana volcano. Active fumaroles can be seen above several vents in the hydrothermally altered summit region. The main edifice was constructed primarily by lava effusion, with late-stage eruptions producing an accumulated pile of short, thick lava flows. Flank vents have also emitted fresh-looking lava flows.
