LaGrange Equilateral triangle on Earth’s crust
Finding that ET has a volcano at one corner and anomalies at the other 60,60 degree anomalies, I measured from Erebus, Antarctica 16,000 km north to Canada’s craton- Hudson Bay slice on the south side (see first Google Earth photo), James Bay- which is almost along a meridian and undistorted by a Mercator projection. Cratons of Canada and Australia are 16,000 km apart, but now not along a meridian 144 degrees apart, as at the start. Australia’s craton “outback” above has an anomaly shown, which seems to fit the curvature of an anomaly and subject to doubt, without further evidence. Now look at the angle made so far. It’s not 60 degrees, as found from other LaGrange triangles, but 120- which is 180-60: James Bay has Canada’s craton on the East side, and is 16,000 km from Mt. Erebus active eruption in December 2014; this line is nearly on a meridian, so that it’s approximately correct- unlike the line to craton center in Australia. Angle is not 60 degrees, but closer ...
