Because of its geographical setup on the perimeter of the Klang Valley, the quartz ridge we hiked comprised a boundary between two worlds. On the southern side was a world of sprawling urbanization conceived by human engineering and the northern side was lay dark green jungle in its simplicity and wilderness. On this side there was a placid mist enshrouded lake. There was a sort of gate where the ridge dipped low at one point, from here water from the lake was piped to the city and flocks of various species of birds would traverse back and forth.

This is a picture of the 'gate', where the ridge dips low. It is hard to perceive because it was taken from the ridge itself. It cannot be seen in this photo but to the right of the ridge begins the creep of urbanization.
At the higher altitude, there were carpets of moss due to the constant humidity and frequent rain.
