Global Volcanism Program | Image GVP-07706

The vegetated lava flows in the middle of the photo traveled short distances to the south from Xitle flank vents, the scoria cone in the background. Most lava flows followed the topographic gradient to the north. Scoria-fall deposits from the 150-m-high pyroclastic cone mantle the foreground and overlie parts of the lava flows.
