I need help finding the elevation points for each point on image 1. The following questions are for image 2: What is the contour interval? What are the elevations of lines A and B? Provide an approximate elevation for points W (point is inside the circle), X, and Y (point is on the line).

Contour maps can be intimidating to look at. A helpful trick is to find two index contours that are somewhat spaced apart, in order to count how many contour lines are between the two index contours. Once that is known, you can figure out what the map's contour interval is. For map 1, the 6,000 foot marker is just south of the red circle. Follow that down and around to the east and then back north, until you are parallel with point "X." Directly underneath "X" is the 5,750 index contour. Based on the number of lines between the 6,000 line and the 5,750 line, the contour interval of the map is 50. Going west of the 5,750 line to point X gives a rough elevation of between 5,950 and 6,000.
Point "W" is much easier. It's right on the 5,750 line. Point "Z" is also right on the 5,750 line. Point "Y" is just a bit west and downhill from "Z." It's past the next contour line, so it has to be below 5,700, but it's also above 5,650, because there isn't another contour line before that point.
Map 2 is simpler to interpret, because it's not so "crowded- looking" with contour lines. The index contours are 100 feet in elevation different. Using that, along with the number of lines between the indexes, gives us the contour interval of 20 feet per line. Point "Y" is right on the 400 line. Point "W" is inside the 300 line, but no other lines appear. This means it has to be greater than 300 and less than 320. Points "A," "B," and "X" are on or near special contour lines, with little perpendicular stubs hanging off of them. Those signal a depression in the ground. This means that point "B" is at an elevation of 60. "A" is at 80. "X" is somewhere between 40 and 20.
