1) 40 degrees south latitude, 20 degrees west longitude
2) orchards, scrub, vinyards
3) The marked contours are 400 feet apart, there are 4 unmarked
contours between each of those.
So there are 5 contour intervals (spaces between contours) between 400 feet.
400 ÷ 5 = 80 ft
4a) 1/62,500
4b) 62,500
4c) 0.99 mile (62,500in ÷ 63,360 in/mile = 0.99 mile)
9) The bearing from C to D is:
North 24° east; azimuth of 24°

17) Click here for a sloppy version of
a cross section (this isn't perfect by a long way, but it's a good
start and if you can get yours to look like this then you'll be fine! If you'd
like more details on how to make this even better, contact your TA!).
Vertical exaggeration is about 13.75 .
How did I get this number?
How far is one inch on the map (horizontal scale)?

35) 7 degrees west declination
36) Published in 1945 (though originally surveyed in the early 1900's,
there is no indication that this is a later edition of the map.)
37) fractional scale = 1:62,500
39) 2 inches = 1.98 miles (about 2 miles)
2 = inches = about 3.2 km
