Our altitude
In case you’ve always wondered, our house in Mexico City is at an altitude of 2238 metres (7343 feet).
As a point of comparison, our home in Calgary was at 1075m (3527ft), the Banff Springs Hotel is at 1427m (4682ft). Colorado Springs in the USA is 1831m (6008ft). Mt McKinley (Alaska), North America’s highest peak, is 6194m (20,322ft).
At 2238m, there is only 77% the amount of oxygen that there is at sea level (as compared to Calgary, which has 88%) (see this altitude graph).
And now you know.
