How long in kilometers is this mountain range? 5. How would you describe the shape of this mountain range as mapped out here? 6. Using the map key, which rock formations are the oldest rocks in the Klamaths? 7. Using the map key, which rock formations are the youngest rocks in the Klamaths? 8. Why are there so many different rock types here? How did they get here? 9. Which set of rocks were the first to be docked on to the edge of the North American continent? 10.

1. Using the map to the right, find the Klamath Mountains province and shade (or color) it in. This is the first of a handful of homework assignments where we will create an outline of different features found in California's amazing provinces. Next, let's work with the geologic map of the Klamath Mountains. A geologic map shows the rocks in the area that have been mapped out by a geologist. You'll find rock types, rock formations, ages, and structures (folds, faults), too. Examine the geologic map of the Klamath Mountains and answer the following questions.
