This is my favorite, the "Hummingbird". Nearly 100 meters long, archealogists have dated this over 2,000 years old. The climate lends itself to the preservation of these glyphs. Note - hummingbirds are native to the Americas, not found on any other continent. Also note, at the beak there is a group of vertical lines, up to 500 meters long, believed by some to mark a date equivalent in our calendar to be December 21st.
