Before the hike, study the topographic map at home. Start with the legend: each contour line connects points of equal elevation. The contour interval tells you the elevation change between lines (often 20 or 40 feet).

Learn to read terrain from lines. Contour lines packed tightly together = steep slope. Lines widely spaced = gentle terrain. Concentric circles = hilltop or peak. V-shaped lines pointing uphill = valley or stream.

Find your planned trail on the map. Trace it with your finger. Predict the experience: "Here the lines are close together — we'll climb steeply. Then they spread out — it levels off. Then I see a stream symbol."

Orient the map with your compass before starting the hike. Rotate the paper until north on the map matches north on the compass. Now everything lines up with the real landscape.

Hike and compare. Stop at your prediction points. "The map showed bunched contour lines here — is it steep? Yes!" When the map matches reality, the connection clicks.

Mark the map with your own observations — an unmapped stream, a great viewpoint, a fallen tree blocking the trail, wildlife sightings. You're updating the map with ground truth.

Topo map reading is one of the most useful outdoor skills. GPS batteries die, phones lose signal, but a paper map and compass always work.

Start with a simple area — a park with one clear hill. Don't begin on a complex mountain trail.

Build a 3D contour model at home: trace contour lines onto cardboard, cut them out, and stack them. The physical model makes the 2D-to-3D leap concrete.

This skill connects to geography, math (scale, measurement, angles), and spatial reasoning. It's genuinely cross-curricular.
