The work shows volcanic rocks rising from the ground that create trails of pixels. The layering of tezontle is generated by a software by modifying the size, speed, trajectory and selection of rocks from a database of photogrammetric 3D scans. Made in November 2019 in collaboration with UNAM’s Instituto de Geografía during a residency for Connecting the Dots, the work is related to research on the impact of mining activities in extinct volcanoes of Sierra de Santa Catarina located south of Mexico City.
