Photo: N.Z. Forest Service (J.H.G. Johns, A.R.P.S.) This view shows two bad slips, which are being further eroded by the formation of gullies. There are numerous smaller slips, and between the two large slips there is seen slumping that may develop into another large slip. Note how the products of erosion are filling the valleys. Erosion of this kind is brought about largely by removal of the original vegetative cover; but the nature of the underlying geological formations, the amount and frequency of rainfall, and other matteras have to be considers when control measures are eing planned. (Upper Waipaoa River, Poverty Bay.)
