First Paragraph

“Steep Cliffs!” warns a map of California’s Point Reyes National Seashore, 72 kilometers northwest of San Francisco. “The cliffs of the Point Reyes Headlands are likely to crumble and slide,” the notation continues. “Climbing on them invites catastrophe. Because of falling rocks, walking below cliffs is dangerous. Keep away!”
