EAS 100-51: EARTH SCIENCE
 
HIGHLAND PARK, ILLINOIS - 7.5 MINUTE QUADRANGLE (1963 version)
TOPOGRAPHIC MAP EXERCISE (Revised)

For questions 1 -> 5, give the correct Township-Range grid locations of the following landmarks or topographic features on the map:

1.    The water tank, near Green Acres Country Club, north of Route 68:

 SE 1/4 of SW 1/4 of Section 2, T42N, R12E

2.    The waterworks, at the extreme southeast corner of Fort Sheridan:

SW 1/4 of NE 1/4 of Section 14, T43N, R12E 

3.    Bannockburn School, along Telegraph Road, west of Waukegan Road:

SW 1/4 of NW 1/4 of Section 20, T43N, R12E 

4.    Red Oak School, north of Clavey Road, east of N. Branch Chicago River:

SE 1/4 of NW 1/4 of Section 34, T43N, R12E 

5.    Sportsman Country Club, south of Route 68, 1/2 west of Landwehr Road:

NE 1/4 of NW 1/4 of Section 8, T42N, R12E 

6.    What is the highest topographic elevation point in the SW 1/4 of SE 1/4 of Section 12, T42N, R12E? Where is this land located?

640 feet
The Skokie Lagoons

7.    Locate the NE 1/4 of SE 1/4 of Section 3, T42N, R12E. Are there any contour lines which indicate a depression rather than a hill? What is located inside this feature?

Yes, there are hachure lines which radiate inward towards the center, indicating a depression (perhaps a rock quarry?)

8.    What is the longest distance (to the nearest 100 feet) covered by the Skokie Lagoons? What is this distance in miles (to the nearest 1/10)?

About 11,100 feet
About 2.1 miles

9.    Note the pattern of contour lines along the shoreline of Lake Michigan. These are known as the Highland Park bluffs. How steep of a drop is it from the top of the bluffs into the lake? What geological processes produced the bluffs?

There is at least a 50 foot drop from the top of the bluffs to the lake. The bluffs were caused by wave erosion from Lake Michigan.

10.    Why do the contour lines of the Highland Park bluffs extend inland, some as far as one mile?

These are called ravines, which are embayments caused by both the melting of the last glaciers and periodically rising lake levels.

11.    What distance in feet is covered going East to West, along the southern boundary of this map?

About 38,000 feet.
