From there the line continued west, maneuvering down a more than 1,500 - foot [more than 400 m] drop into the Rift Valley and then up the other side through dense forests and over deep ravines until it reached Mau Summit, at an altitude of 8,700 feet [2,600 m].
Sealt kulges tee edasi lääne poole, loogeldes rohkem kui 400 meetrit allapoole riftiorgu ning sealt üles läbi tihedate metsade ja üle sügavate kuristike teisele poole orgu 2600 meetri kõrguse Mau tipuni.
