The watershed of the Amazon basin begins in the high Andes. In Ecuador, the continental divide is adorned by a string of massive, glacier-capped stratovolcanoes. One of the most impressive of these giants is Cotopaxi, which at 5,897 m (19,347 ft) is Earth’s highest active volcano. Steeped in lore and considered a sacred mountain by local Andean peoples, Cotopaxi has erupted more than 50 times since 1738. There has not been a major eruption since 1904, but minor eruptions have occurred as recently as January 2016. A major eruption in the future a concern for Quito, Ecuador’s capital city, due to its close proximity to the volcano. Past major eruptions have produced pyroclastic flows, melting the icecap and forming massive lahars - or volcanic mudflows - that destroyed local towns and traveled more than 100km to both the Pacific Ocean and Amazon basin.

Tensions mount among some fiesty black-faced impala (Aepyceros melampus petersi).

Although impalas themselves are not endangered, this distinctive subspecies (found only in northwest Namibia and Angola) has fewer than 1,000 surviving individuals still in the wild. The black-faced impala is easy to distinguish from other impala in that they are significantly larger and carry the black facial markings seen here.

It was very difficult for me to choose just one photo for Day #6 of my ‪#‎challengeonnaturephotography‬. I feel like I need 20 more days to show you all the diversity of landscapes and life I encountered in beautiful Namibia.

The camelthorn trees of Deadvlei  are believed to have died 600 to over 1,000 years ago when shifting dune sands blocked the Tsauchab River from reaching this once desert marsh.

This is my submission for day #5 of my ‪#‎challengeonnaturephotography‬.

The extinct marsh of Deadvlei lies adjacent to the even more well known salt pan of Sossusvlei. The pans are surrounded by some of the oldest and tallest - perhaps THE tallest - dunes in the world. The highest dune here was actually behind me when I took this photo. It's called "Big Daddy" and stands about 380 metres high, the same height as the +Empire State Building.

The dunes are a highlight of the Namib-Naukluft National Park, which with an area of 49,768 km2 (19,216 sq mi) is the largest game park in Africa and the fourth largest in the world. The park is larger than Switzerland or, in other terms, equal to the US states of New Hampshire and Vermont combined.

The shades of pink, orange and red are an indication of high concentrations of iron in the sand, with the deeper reds being found on the older dunes. In a very real sense, these dunes are "rusty".
