Ander Andersen is another new contributor. He kicks off with marker for the geographic center of the US. UK readers please forgive the US spelling of what should be “centre” but given the location I thought I should follow their convention.
Of course anything that claims to be the geographic centre of a country or polygon is going to prompt some discourse in the geo community. The marker has Lat 39 degrees 50 minutes, Long 98,35 but, as you might expect Wikipedia has a whole article about the different options – this marker is at the centre of the 48 contiguous states and located Lebanon, Kansas
If you include Alaska and Hawaii the centre shifts to Lat 44,58, Long 103,56 which is north of Belle Fourche in South Dakota.
