Textures associated with volcanic landslides are preserved in this quarry wall more than 100 km from the source of this major avalanche from México's Colima volcano. Large fractured blocks appear at the top of the exposure, and a color mottling is produced by adjacent segments of the volcano or valley floor material incorporated during transport. A 2-m-high ruler provides scale.
