To find Dewey think of a food that you eat.
It is sometimes spicy and sometimes sweet.
The country we are in shares the same name.
The spelling is different, but they sound the same.
Geo and I pretended to laugh off the clue as an advertisement for a tourist place so Nora would not realize how important it was after all. We talked as we hiked back off the mountain and left Nora as we went into our hotel.
We got right back to the clue: The picture looks like a mountain. Our next destination is a country with the same name as food. The country has mountains. Can you look at the map of South America and tell us where to go next?

Here is the photo of Dewey that was with the clue in the brown envelope.
Map of South America
Here is a map to use to try to find the name of the city listed in the clue. Did you figure it out?
From the return address on the envelope, Meri and I think that Dewey may be in this very hotel, so we are off to investigate. While we are gone, see if you can figure out the coordinates for Chile (longitude and latitude). The numbers on this map are a bit hard to read, so I will help you out a bit. Across the top, the lines of longitude are 80, 60, and 40. Down the side of the map, the lines of latitude are 0, 20, and 40. Good luck!
Text Message from Pandora: RUOK? J2LYK - I got a strange email that said "the key is in NW Passage". PLS write ASAP.
Text Message to Pandora: Hey. We R great in Chile. ABT2 look for Dewey. Thanks for clue - shhhhh! BBFN.

Can you figure out the coordinates for Chile (longitude and latitude)? The numbers on this map are a bit hard to read. Across the top, the lines of longitude are 80, 60, and 40. Down the side of the map, the lines of latitude are 0, 20, and 40.
Geo and I decided we better look at these documents and see if they gave us any clues to where Dewey may have been taken or about what the Northwest Passage means. The first document was a flyer about the "African Star," a small cruise ship that was departing Chile tomorrow morning. The second document confirmed a reservation for tomorrow morning, flying 2 adults (and 1 large crate) from Santiago, Chile, to Addis Ababa, Ethiopia. Holy Idaho! I am so glad we found this reservation - we are packing now and heading to Addis Ababa first thing tomorrow morning. Tomorrow we will also try to figure out what the Northwest Passage is and how it is involved in this mystery.
When we arrive in Addis Ababa, what should we do first? We could question the airline employees from the airline that the "Equators/Herrings" traveled on, call Uncle GT and see if he has any information about the Northwest Passage, or call the local hotels and find out if there is a couple by the name of "Equator" or "Herring" staying at that hotel.

equator - an imaginary line on the earth's surface that is positioned halfway between the north pole and the south pole. The equator divides the earth into the northern hemisphere and the southern hemisphere.
inhospitable - a place that has a climate and conditions that make it hard for many plants and animals to live and grow.
latitude - the lines that run across (east and west) a map. Lines of latitude measure degrees via north or south. The equator is at 0 degrees latitude.
longitude - lines that run up and down the map (north and south). These lines are used to measure degrees east or west from the prime meridian. The prime meridian is located at 0 degrees longitude.
southern hemisphere - the half of the planet Earth that is south of the equator. The southern hemisphere contains all of Antarctica and Australia, most of South America, and part of Asia and Africa.
tsunamis - an enormous ocean wave that is produced by a landslide, volcanic eruption, or a sub-marine earthquake.

Grade 3-5: Uses map grids (e.g., latitude and longitude or alphanumeric system) to plot absolute location.
Grade 6-8: Understands concepts such as axis, seasons, rotation, and revolution.
Grade 3-5: Knows major physical and human features of places as they are represented on maps and globes. Knows how to read different maps: road, relief, globe, etc..
Grade 3-5: Knows the approximate location of major continents, mountain ranges, and bodies of water on Earth.
Grade 6-8: Knows the location of physical and human features on maps and globes (e.g., culture hearths such as Mesopotamia, Huang Ho, the Yucatan Peninsula, the Nile Valley; major ocean currents; wind patterns; land forms; climate regions).
Grade 3-5: Knows different methods to measure data (miles, kilometers, time, etc..).
Grade 6-8: Understands distributions of physical and human occurrences with respect to spatial patterns, arrangements, and associations (e.g. why some areas are more densely settled than others).
Grade 6-8: Understands criteria that give a region identity (such as Amsterdam as a transportation center or the Sunbelt's warm climate and popularity with retired people).
Grade 3-5: Knows the physical components of Earth's atmosphere (weather and climate), lithosphere (land forms such as mountains), hydrosphere (oceans, lakes and rivers), and biosphere (vegetation and biomes).
Grade 6-8: Knows the consequences of a specific physical process operating on Earth's surface (e.g., effects of an extreme weather phenomenon such as a hurricane's impact on a coastal ecosystem, effects of heavy rainfall on hill slopes, effects of the continued movement of Earth's tectonic plates).
Grade 3-5: Understands how cultures differ in their use of similar environments and resources (for example, comparing how people live in Phoenix, Arizona with how people live is Riyadh, Saudi Arabia).
Grade 6-8: Understands the symbolic importance of capital cities (such as Canberra, a planned city, as the capital of Australia).
Grade 3-5: Knows natural hazards that occur in the physical environment (floods, tornadoes, earthquakes, etc..).
