Since we have Google Earth a lot of formerly unknown prehistoric monuments have been found all over the world.
The Sahara desert is full of such artifacts of different shapes.
Throughout the whole of the Tassili N'Ajjer, down to the Hoggar Mountains, there are elaborately constructed stone monuments, whose shape resembles keyholes. Therefore they are called "Monuments en trou de serrure" or "Keyhole monuments". According to current knowledge, these keyholes are probably the oldest of the known Sahara monuments. Dating has shown an age of up to 7,000 years. However, their function remains unclear somtimes. Some of them were clearly graves, others had no evidence of funerals.

..., why not share all the related placemarks, I collected within the past fifteen years...
-15 years? -why not? -just the same by me with my mounds!
Only, that I do not have such cool homepage as you do! - Really: congrats for the site and many thanks for sharing all you have explored through the years!
I know some Africa experts with 30.000+ markers of pre-islam, (proto-berber?) monuments, but with not much care of representation. I think was a big work for you making such amount of screenshots, but that is what gives the advantage of your database.
I have noticed low-resolution stripes on GE with no markers on them. When I bump into such low-res areas I do not stop the search for further pieces, only I start ZoomEarth (and/or Bing, and/or ArcGIS) with alternative satellite imagery so as I can continue mapping (giving hi-res ZE-links in low-res GE-placemarks' descriptions).- This way you might find placemarks by me, those are new to your collections - Please feel free to include them into your dataset! (citation: syzygy@GEC 2020)
All for the types you will find placemarks (sorry, nomenclature would need a major update), and even for more... What do you know (think) for example about the ones, I dub 'rondelloids'? (purple-star placemarks in my collections) As my latest knowledge these are not studied before, also research is anchored by now because of the unfavorable political situation of the area. (?) ...
...How you've been able to englishize my nickname, which normally not even gemans understand realy? I guess you are German or at least bi-lingual.
Nope - only, that I am hungarian ( : also I like (word)-jokes very much and frequently I do "nick-analytics" by new-members. I have known the word "Welt" (I have seen it on German made maps), and typing "bemerkensw.." into GTranslator, it offers the phrase "bemerkenswert" I did not know before, but it was easy then...
In high-school (some 25 years ago) I had 4 unpleasant years of having German-language lessons 2 times a week, but I have "resisted"... sorry, since I have never could forgive your language that evil "Der, Die, Das"! ..((( :

syzygy: For single or a few placemarks coordinates still fine of course!

syzygy: Yup! Sorry everyone for the attachment issue! Hope will be solved soon! Until links to kmz files stored elsewhere is can be a solution...

RaveyThirteen: So... I just tried to add a .kmz of some new finds and saw that nasty error message. Should I just hold onto it til the space issue is sorted?

typsish: As far as I know, it should be foldable. But check the rules of the company you are flying with. They have the specific requirements mentioned in the luggage section. And if the stroller you have now doesn't fit their requirements, check the article on new

diane9247: I don't know what to do about the "space limit" thing. I got a post ready, then couldn't upload the small file. I am losing eyesight, so not sure I can even post anymore! 😵💫(Pinned unfinished post last night, but it didn't save.)

willi1: GE Imagery Date: Yes, I noticed it too. And I thought it was something of an attitude on my part.

SpiderX22: In regards to this error - on my forum posts/threads -> I can start compiling attached files into one kml collection to slim down attachment numbers

SpiderX22: Also - a heads up: Error: This forum has exceeded its attachment space limit. Your file cannot be uploaded.

SpiderX22: Anyone else notice that new Google Earth imagery doesn't have a date anymore?
