Looking at the landscape without a geologic map is like travelling in a foreign country without speaking the language. One can see many fascinating things, and perhaps even understand and interpret a few, but much of the deeper understanding inevitably lies shrouded in mystery.

Without knowing French, for example, one can only guess at what is on the menu or what those standing next to you are saying (but it’s something important, you’re sure!). Even reading a foreign newspaper is an exercise in fultility.

It is no different with geology. Without a geologic map in hand, reading and understanding the landscape - particularly its immensely long and varied geologic history, its resources, and its hazards - can only be done at a superficial level.
