Here we see the depth of the layer at which a temperature difference of 170K to the surface conditions is reached. The grey
land regions are regions where the next measurement registered within the data collected by the International Heat Flow Commission (IHFC) is more than 300 km
away. The darkest blue indicates regions where the depth of the 170K layer is below 6000m.
