Think we tried this once before. If you go to 28°19'53.02"S 30°43'48.95"E and drag the streetview icon to that point, pan to the left. You are then looking straight down the Qwabe valley, the slight ridge half way down is the point Durnford reached riding out from the camp. 'Drive' along till you reach 28°18'58.79"S 30°43'6.54"E pan to the left you will see the road sign to the lodge. The stream crossing the road is the Ngwebini stream. The area to your left up to to the main ridge is the area THFHT designates as the area the the impi was located in. Way over behind the ridge is isandlwana itself.
Give it a go once you get the hang of street view you can look down to Chelmsfords breakfast spot, the mangeni gorge and a whole lot more.
If you cant make it work do as i do and get your hands on a 10 year old to show you.
