Thermal Inversion Over Thimphu Valley at Dusk

Distant amber light from Thimphu glows on the horizon beneath a sharp, clear summit. Below the rocky saddle, a thick blanket of gray smog fills the valley floor, suspended by a thermal inversion layer. Low-hanging clouds drift within the fog bank, their edges soft against the darkening green slopes of late spring. The foreground shows rough, weathered granite stones of the saddle, stark and shadowed against the bright sky above. A layer of mist separates the cold, solid rock from the hazy warmth of the town far below. The boundary between the clear air and the trapped pollution forms a distinct, horizontal line across the entire landscape. Shadows stretch long across the granite ridge.
