But, today, with the sun shimmering mirages of blue diamonds on Sterkspruit Dam, there is no reason to think of the battles fought on the fields of Spionkop so nearby. The monument to the trek is further inland, the three monuments (to native, colonizer and something else somewhere between the two) at Spionkop are inside a national park, Kimberly is about four hours away to the southwest, the original reef of Witwatersrand about two to the north.  There is only the blue and the green and the road, black with bits of white and yellow, through it.  Not a trace of the people who passed through here on their way to somewhere else, somewhere better or worse or just new.  Not a trace.
