I am subscribed to this YouTube channel by Brian Forester, who travels megalithic sites the world over and he brings his drone with him lately and gets some awesome footage. A lot of the megalithic sites he goes to are unheard of by most tourists so its a real adventure to watch him and his videos.
His latest one is a carving in Peru near Killarumiyoq. Some people say it is a great incan carving of either a sun calendar or a moon calendar. Whatever it is, it is very interesting.
