The Kariba Dam Observation Point

Grid Ref (WGS84 Lat/Long in decimal degrees)

Location: 
The Kariba Dam Observation Point
Description: 
The steps ascending to the interpretive centre (beneath the crochet work) at the Observation Point, and those beyond, reveal banded Kariba Quartzite, with apparent biotite gneiss interleaved in either bedded or thrust relationship.  It is in this situation where weathering is deep and where the dip corresponds with the hill slope, landslip took place threatening to disrupt the tailraces on the south bank.  Extensive drainage, rock bolting and slope sculpture has aleviated this threat.  The weathered contact on the south dam abutment was also associated with a highly weathered ‘mica band’, which was replaced by concrete buttresses to take the dam thrust – hence the south-bank car park.
