4 Topographic maps: Go to topozone.com/Maryland. Make sure you click the square on the left side to go into full screen mode- gets rid of the annoying ads. Also click on the layers button on the upper right and make sure “topo” is checked. The map should turn greenish if you did it right.

Then: zoom in and find Laurel Maryland and nearby is Maryland city. Just East of Maryland City is Fort George Meade Military Reservation. Slide the map so that is in the center and zoom in or out so you see the Patuxent River at the bottom and the Little Patuxent River at the top. Finally, right below the words “Military Reservation”, you should see “Switchboard Road”.

Answer the following (next page): 4 pts total
