A Beautiful parking lot - waterproofing the land
Composites of rocks/gravel. Grey, orange, brown and white.
Parking lots cause many of the erosion problems in he ravines. Run-off from the lots flows into large drainage pipes and pours into the ravines in small, concentrated areas. If the large plateaus above the ravines were not tarred over they would absorb much of the rainwater wan the ravines would not be eroding 3 cm per year.
