We headed on to Laguna Colorada. We arrived in the mid-afternoon and the lake was bright red, with flamingoes dotted all across the waters. What looked like steam rising from the lake in the distance was apparently salt water whirlwinds, a common site here. We were staying here for the night, at Campamento Ende, a meteorological station on the south-western shore of the lake, and we were all now feeling the altitude. My trip to El Tatio had definitely done me some good, acclimatisation-wise, as had the trip up to Sol de Mañana and back down to here, and I went for a walk while the others rested, but I was still totally exhausted if I walked even a few metres uphill. I took a lot of photos of the lake, which was getting redder and redder due to mineral reactions in the sunlight, and the thousands of flamingoes strutting about in the shallow waters.
Night fell not long after 6pm, and the temperature plummeted. I stood on the shores of the lake, breathing the thin cold air and watching a thunderstorm in the distance, until 9pm when the generator at Campamento Ende was shut off, and the only light was coming from the moon. I went to bed exhausted by the altitude and slightly dreading the 6am start we were apparently planning for the morning.
