It's vacation time, and most likely there is a map involved, especially if one is traveling to a new destination. Early explorers to the Chesapeake region had maps, too. The key lines/numbers on their charts were not highways and mileage charts, but latitude (distance from the equator) and longitude lines (distance from the prime meridian at Greenwich, England). To learn more about these lines See "Past is Prologue," January-February 2003.

Below are 10 cities in the Chesapeake Bay watershed and 10 latitude and longitude coordinates, in degrees and minutes. See if you can match them up without peeking at a map!

Annapolis, MD
Baltimore, MD
Cooperstown, NY
District of Columbia
Harrisburg, PA
Martinsburg, WV
Norfolk, VA
Richmond, VA
Scranton, PA
Seaford, DE

  3. 38° 51" N, 77° 2" W
  4. 36° 54" N, 76° 12" W
  5. 38° 59" N, 76° 30" W
  6. 40° 12" N, 76° 18" W
  7. 39° 26" N, 77° 58" W
  8. 38° 38" N, 75° 36" W
  9. 42° 42" N, 74° 56" W
  10. 41° 25" N, 75° 45" W

(Hint: Remember, the larger the number of the number of the coordinate, the farther away it is from the equator and prime meridian. Thus, #6 would be the northernmost city and #7 the westernmost.)
