Well, GG has from time to time pointed out mistakes in graphics in papers, so it is only fair that he share a mistake in his graphics pointed out by others. In Jones et al. (Geosphere, 2011), several panels of Figure 2 place the frontal thrust faults of the fold-thrust belt in the wrong place in Montana (to be clear, this is the upper left part of the full figure seen at right or below):
The black line with barbs was to represent the eastern limit of the fold-thrust belt, but GG apparently mistook a high-angle Laramide-style fault for a low-angle thrust connection up to the Helena Salient. The proper line would be close to the red line in the figure above.
So a question to any readers is, do you think this merits a published correction?
