Members of the ROTTnROCK team on their trip to study hydrothermal alteration and volcanotectonics in Chile. See the screw in the tyre? That's tyre number 2. We need another spare!

I see altered rocks! 😍

A panoramic view from the top of Lascar volcano, ~ 2 years after its last eruption. The air is thin up there!

Drone image at 5800m showing the crater of Lascar volcano, looking north. See the little people in the foreground? That's us.
