Harald Blatand died about a thousand years ago, but his name has become more famous in the third millenium than it ever was in his own time!
First, you have to find out what the IEEE call his namesake (ABC.DE.F)
Then, go to S 31° 58.(ABC-432) E 116° 03.(DEF-151) and use your special equipment to see what name Harald's namesake is using now. You should see a white box with a "21" on it, but you might need to move a little closer to the house. Feel free to ring the bell if the hour is a reasonable one!
GZ is quite near to a big brother of Wpt1, at the base of a tree, hidden by pine needles.
