“I looked at both links. The first one showed a road in some very flat land, with no sign of sand dunes, even relatively low ones.”
Duh...while you are on the road in the Google Steetview panorama, you’re sitting atop one of the stripes in your pictures that you claim to be human made canals. No canal, imagine that. Yes, the land is very flat, nonetheless you are looking down a road that travels across dunes and the valleys between the dunes. You cannot see the dunes, because, as was said before in prior posts, the dunes have been degraded in the past tens of thousands of years until they have been leveled into relatively flat lands and the valleys between the dunes filled to produce relatively flat lands. The stripes visible in the satellite and aerial views result from the differences in chemistries between the soils of the whitish silicate and calcium carbonate rich degraded linear dunes and the reddish clay filled valleys between the linear dunes. While traveling down the road in the Streetview, you cannot find any canals, because they quite simply do not exist except in the minds of the gullible, who insist upon the existence of UFO alien engineers and like fantasies.
“I don’t know if there was some way I was supposed to make a long trip down the road in the various places, but all I managed was to turn around in the other direction.”
That location was reached by using Streetview to travel on the roads out of the Tsodilo Hills UNESCO World Heritage Site and towards the southeastern and eastern areas beyond them. The Streetview function becomes problematic at about the point of the picture. Using Streetview in the vicinity of the Tsodilo Hills site gives you an opportunity to witness no canals exist where the Google satellite views show the colored stripes on the ground. Instead, Steetview demonstrates how the ancient linear sand dunes and valleys between them were leveled by aeolian forces and erosion to produce soils differing in coloration in a striped pattern.
“No travel across anything that might have been an excavated area that I could figure out how to make happen.”
Streetview can work from that location and along the road/s back to the Tsodilo Hills. When you get your computer and Streetview to work properly to travel down the road, note how your position in the satellite view travels directly across some the same features seen in the Google satellite view you are erroneously claiming to be canals/ditches.
“The spooky music was interesting, but not relevant”
It is relevant because it is mystery music accompanying your fictional mystery canals.
“Do you happen to have any scientific basis for your rejection of the canals idea.”
Why are you pretending to be ignorant of the scientific sources referenced in the previous posts?
“I had a year of geology, and we saw a lot of pictures of various kinds of landscape, and nothing with sand dunes created anything that looked like this area.”
Evidently you failed to benefit from your college education in geology, otherwise you would have immediately understood our prior comments about “degraded” linear sand dunes and their obvious relationship to the formation of sedimentary soils and rocks. Sand dunes, linear and otherwise, which persist long enough to become consolidated and embedded into the soils are in the transition to becoming sandstone and limestone. Degraded sand dunes in sedimentary units was a common feature in our geomorphology surveys.
“So unless you can show me something specifically scientific that refutes them, I am sticking with my interpretations.”
Why do you choose to deny the sources already provided to you in prior posts which reported how cores were taken from the sand dunes?
Establishment scientists often refuse to see/acknowledge material which does not fit into their previous views, or coworkers and superiors who might judge them and affect their grants, employment, and futures. Witness the current change in “before Clovis” thinking, and search now for underwater signs of civilized development when sea levels were much lower at the end of the Ice Age.
