Hello, I see the incorrect Wikipedia article on 'Blue Hills, Turks and Caicos', which has no references. It is simply incorrect. Unfortunately it seems like several people have copied and relied on it. I have the OS maps made by the UK from the 1960s and Blue Mountain is 156 feet, and the pin that was on the map is around 50 feet. As a note, I live on the island and can quite assure you 'Blue Hills' is not a mountain rather a residential community. Here's an article from our website which explains a bit more: https://www.visittci.com/providenciales/blue-mountain
