Northward view of Tasman River valley showing braids of the river entering the northern end of Lake Pukake, New Zealand's largest man-made hydro-electric storage lake. The cloudiness of the water in the foreground is due to glacial rock-flour. Mt Cook is seen in the far distance centrally in the picture. Image 14 in this collection is a southward view of the Tasman River valley and Lake Pukake with tributary rivers entering from both sides of the valley.
