An ash plume rises from the summit crater of Parícutin sometime during 1946-48. A thick ash deposit covers the foreground. An estimated 4,500 cattle and 550 horses died during the heavy ashfall in the early months of the eruption, devastating the local people who depended on the animals for food, plowing, and transportation.

Beryl Spring is a hydrothermal area in some restrictive topography! The road from Norris Geyser Basin to Madison Junction follows the Gibbon River through a tight valley. With not much of a choice, the road threads between the river and Beryl Spring over some exceedingly hot ground.
