To experience geology in perpetual motion, says Collier, visit a beach. “Coasts are among the most dynamic landscapes on earth,” he writes. “Nowhere else on earth is so much going on at once.”

Collier notes: “La Sal Vieja has provided salt to Texans and their predecessors for hundreds of years. Rainwater that occasionally fills this lake becomes saturated from an underlying salt dome; high evaporation rates in this hot, dry climate leave the lakebed coated with powdery white salt.”
