1. Draw a North Arrow on the geologic map of the Centralia area.
2. The distance between Centralia, PA and the small town of Lost Creek on the east edge of the map is approximately seven miles. What is the scale for this map?
3. Look at the geologic map and determine what rock unit or formation contains the coal at Centralia. What is the name and age of this unit?
