In this highly physical outdoor activity, learners construct and compare experimental trail sections to select the best trail-construction technique for their site. As they measure, evaluate and build, they must consider factors including erosion, slope, materials, labor, cost, human effort, and various environmental impacts. The slope measuring component not only involves mathematical problem-solving, but can incorporate measurement of human health performance, since one way of measuring slope in this activity can be having learners check their pulse as they climb a hill. This activity can be well combined with the "Hold a Hill" and "Cardiac Hill" activities from the same resource.
