Understanding the Map

This is a topographic map showing elevation using contour lines. Key features:

- Contour lines connect points of equal elevation.
- Closely spaced lines = steep slope; widely spaced lines = gentle slope.
- Closed loops with higher values inside indicate hills or mountains.
- "X" marks the highest point on Rock Mountain.
- Elevation is in feet.
- The contour interval is the difference in elevation between adjacent contour lines.

Step 1: Determine the Contour Interval

Look at the labeled contour lines:
- We see 800, 900, 1000, 1100, 1200, 1300, 1400, and 1500 feet.
- These increase by 100 feet each time.

✔ So, the contour interval is 100 feet.

> Answer to Question 2:
> Contour interval = 100 feet

Step 2: Find Elevations at Points A, B, C, D

We use the contour lines and the rule that:
- If a point is on a contour line, its elevation is that value.
- If it’s between two lines, estimate based on proximity.

---

#### Point A
- Located on the 800-foot contour line.
- Also near the lake (lakes are at low elevations).

✔ Elevation of A = 800 feet

---

#### Point B
- Lies on the 800-foot contour line.
- It’s along Fish Creek, which flows downhill, but the point is exactly on the 800-ft line.

✔ Elevation of B = 800 feet

#### Point C
- Located inside the 1500-foot contour line, but outside the 1600-foot one?
Wait — let’s check carefully.

Looking at the map:
- The outermost labeled contour around Rock Mountain is 1500 ft.
- Inside that is another closed loop labeled 1600 ft? Wait — no.

Actually, looking at the map:
- The innermost contour is 1600 ft, then 1500 ft, then 1400 ft, etc.

But wait — the labels go:
- From the outside: 800, 900, 1000, 1100, 1200, 1300, 1400, 1500, and then 1600 in the center?

Wait — no: the label "1500" is shown just outside the innermost circle, and "1600" is not labeled, but we can infer.

Wait — actually, look again.

The map shows:
- Outer ring: 800
- Then 900, 1000, 1100, 1200, 1300, 1400, 1500
- Then the innermost closed loop has no number, but there’s an "X" marked at the peak.

But note: the label "1500" is placed outside the innermost loop, and the next one inward is unlabeled, but since the contour interval is 100 ft, the innermost loop must be 1600 ft.

So:
- The innermost contour (around X) is 1600 ft
- Then 1500 ft (next out)
- Then 1400 ft, etc.

Now, Point C is located on the 1500-foot contour line.

✔ Elevation of C = 1500 feet

---

#### Point D
- Point D lies between the 1000-ft and 1100-ft contour lines.
- It is closer to the 1000-ft line than the 1100-ft line.
- But since it's not on a contour line, we estimate.

However, if it's between two lines, and no intermediate line, then it's somewhere between 1000 and 1100.

But the question asks for elevation — likely expects a specific value.

Wait — look again.

Point D is on the 1000-foot contour line?

No — the 1000-ft line is to the left of D, and the 1100-ft line is to the right.

But the 1000-ft contour line passes through D?

Yes! Look closely — the 1000-ft contour line goes through point D.

✔ So D is on the 1000-ft contour line.

Therefore, elevation of D = 1000 feet
