Here is another classic Berg mystery that I've been meaning to get onto the forums.
Most hikers and several illustrations that I've seen in various books refer to the prominent, pointy peak, distinctly visible from the Ampitheatre, as Mount Amery. It is the one on the left in the image below. Yet the maps (Government survey, Slingsby, new hiking maps and Garmin topographic) refer to the less impressive buttress on the right as Mount Amery (the hiking maps probably simply follow the survey map). So which is peak is the true Mount Amery, and where did the confusion come from? Did the survey maps get it wrong from the start, whereas tradition maintained that it was the peak on the left? It certainly is attractive and a fun grade B scramble, with some lofty views. The buttress on the right is much bigger in size however, and gives some good views into the Mnweni. Their heights are almost identical, I measured the one on the left to be 3140m and the one of the right, 3151m, which for a hand-held GPS is pretty much the same, except that last time I measured both on the same day, leaving my unit on in between, so the buttress on the right is probably slightly higher.
Note: the list of peaks at the back of Barrier of Spears records the height of Mt Amery as 3143m, and confirms that the approach from the escarpment is a grade B scramble (the buttress is a grade A). Furthermore it mentions the frontal route, which, if I remember correctly, was opened up by guys that were mentored and introduced to the Berg by Pearse. All of this indicates that in Pearse's tradition Mt Amery was the one on the left.
