Just tell me you have spent several hours looking over the vast 300+ miles square from high and low and I will stop arguing with you. Cheers. ;-)

Basically Botswana, although some misguided souls have said South Africa. Most of these parallel mark areas are to the south and west of the Okavango Delta. Some may reach into eastern Namibia. Since I have traversed areas several miles wide, crossing several channels at 50 or 100 feet, I would say that there is every little elevation in the mile between the channels. I suspect people lived along the channels, as some do even today, and used the mile between them for hunting and foraging. Some of the channels also hold water for part of the year and can probably be used for fishing.

We have been over this before, I thought it was settled...as the one who posted the original article, I feel guilty, the images had me hooked. However, upon reflection, there’s no way I can see the hand of man in any of this.

https://earthobservatory.nasa.gov/images/77605/linear-dunes-of-the-caprivi-strip

Google Earth - February 1, 2012
KML

In far northeastern Namibia, there is a skinny stretch of land sandwiched between Angola, Botswana, and Zambia. The Caprivi Strip receives more than 600 millimeters (24 inches) of mean annual rainfall and experiences periodic floods, making it almost moist compared to the much drier parts of the country.

On February 1, 2012, the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this natural-color image of the Caprivi Strip just north of the Okavango River (visible in the large image). Here the land is striped, as if a giant had dragged a rake over the landscape. Those stripes are linear dunes, and some are more than 100 kilometers (60 miles) long. Their presence suggests much drier conditions in the past.

Dunes generally form from wind-blown sand over many years. One characteristic of linear dunes is that they tend to remain intact long after the dry conditions cease. And because they don’t migrate like marching dunes, linear dunes preserve dirt and rocks that geologists can later use to understand past conditions.

A study published in 2000 sampled dunes throughout the Caprivi region and found that they likely formed under arid conditions between roughly 60,000 and 20,000 years ago. A study in 2003 concluded that dune construction may have been especially pronounced between 36,000 and 28,000 years ago. After the dunes formed, conditions in the Caprivi Strip moistened enough for the dunes to support vegetation—woodlands on the dune ridges, and grasses and shrubs in the valleys between.

Although studies indicate that conditions in this region were drier when the dunes formed, the dune-building periods seem to have been punctuated by humid periods, as indicated by sediments found in nearby caves and ancient lake sediments. About 16,000 years ago, a humid period prompted the filling of Etosha Pan. Now a saltpan, Etosha withered partly due to drying climate, but also because of changes in river routes.

I don’t know if you ever saw this particular article, but what the first picture shows looks pretty man made to me. Looking at the link you show, that area looks like it could have been dunes. However, if you look at the link below, and especially the first photo I am sticking with the man made hypothesis. What I really would like to see is some serious studies on the ground by someone who is willing to believe at least some of these could be man made. Also have you gone over the entire area on Google Earth both high and low viewing. I have moved along some of the channels for miles at a low altitude and see no indication that the area I was tracking had anything like sand dunes.

https://earthobservatory.nasa.gov/images/51190/okavango-swamp-botswana

excerpt:

The dark-green forested floodplain is about 10 kilometers (6 miles) wide where it enters the view (image left). The Okavango then enters a rift basin, which allows the river to spread out and form the wetland. The width of the rift determines the dimensions of the delta—150 kilometers (90 miles) from the apex to the downstream margin (image right). The apex fault is difficult to discern, but two fault lines define the downstream margin; the faults appear as linear stream channels and vegetation patterns oriented at right angles to the southeast-trending channels at image center.

The channels carry sediment from the Okavango River that is deposited within the rift basin. Over time, a fan-shaped morphology of deposits has developed, leading to characterization of the wetland as the Okavango “delta.”

The greens of denser savanna vegetation in the north give way to browns of the open “thornscrub” savanna to the south, matching the precipitation patterns of higher rainfall in the north and less rainfall in central Botswana. More subtle distinctions also appear: the arms of the delta include tall, permanent riverine forest and seasonal forest (dark green), with grasses and other savanna vegetation (light green) on floodplains.

Linear dunes, built up by constant winds from the east during drier climates, appear as straight lines at image left. The dunes are 10 meters high, and their sands hold enough moisture for some trees to grow on them. Counter-intuitively, the low “streets” between the dunes are treeless because they are dominated by dense, dry white soils known as calcretes...

Thanks for info and links. I accidentally clicked your name and got your home page. Boy that is some big croc!
