The river, when there is sun, offers glints of light amidst the green; the cliffs colored violet in the dusk and red like embers at dawn; and higher up, Ucul, and down below, Cerro del Diablo, and along the tortuous horizontal slope, the blue methylene triangle of the reservoir behind the dam, forever advancing.
