At an altitude of 3,640 m / 11,942 ft is one of the highest major metropolitan areas in the world. The main part of the city is in a valley between the mountains and the growth of the city has literally occurred up hill. I took this shot at a 300mm focal length on a FF camera to flatten the whole area visually.
The wealthy folks live at the bottom of the valley, the middle classes just up the hill and the poorest people live in higher up the hills.
