3. The quadrangle was first created in 1966
4. The North American Datum of 1927 was used to create this map.
5. The scale of the map is 1:24,000
6. A. 1/24,000 x 5m= 5/120,000, divide by 100 to convert to meters = 1200 meters
B. 1/24,000 x 5in = 5/120,000 in divide by 63,360 = 1.89 miles
C. 5,280 ft/ 1 mile x 12in/ 1 ft= 2.64 in
D 1/24,000 = d/3 km, d= .000125km, .000125km x 1000m/ 1 km x 100cm/ 1m= 12.5 cm
7. The Contour interval on the map is 20 feet
8. A. 34*04'26"N, 118*26'21"W
B. 34*00'27" N 118* 29' 59" W
C 34* 07' 13" N 118* 24' 36" W
9. A. 580 feet
B. 140 feet
C. Between 600 and 700 feet
10. The UTM zone of the map is zone 11
11. 3763,000 M North, 362,000 W
12. About 1,000 square meters are contained within each cell
13. 7.5 minute map line graph (y axis is in feet and x axis is the intersections)


14. The magnetic declination of the map is 14 degrees
15. The stream flows south towards the Los Angeles basin
16.

    9. also needed to convert to meters.
    11. UTM should be in N and E coordinates
    12. 1,000,000 sq. m
