Why are geoglyphs not buried?

Question

page 26 WEST Los Angeles Times December 24, 2006. Why can I see it? If it was there for millions of years, why isn't it buried? Everything else is. And. How come theres no fence around the little guy? He deserves protection too. Is this somebodys farm? Why all the tire tracks? What river? And I quote. "looms along the Colorado River" Are there more than two geoglyphs in this picture?

Answer 1

1) Not there for millions of years.
2) It is not buried because it isn't. There might be hundreds of others that are buried. This one isn't.

Answer 2

I googled "geoglyphs" to check my facts and found this from Wiki:
"A geoglyph is a drawing on the ground, or a large motif, (generally greater than 4 metres) or design produced on the ground, either by arranging clasts (stones, stone fragments, gravel or earth) to create a positive geoglyph (stone arrangement/alignment, petroform, earth mound) or by removing patinated clasts to expose unpatinated ground (negative geoglyph).
Some of the most famous negative geoglyphs are the Nazca Lines in Peru. Other areas with geoglyphs include Western Australia and parts of the Great Basin Desert in SW United States. Hill figures, turf mazes and the stone-lined labyrinths of Scandinavia, Iceland, Lappland and the former Soviet Union are types of geoglyph. The largest geoglyph is the Marree Man in South Australia."

So. I didn't see the newspaper article you refer to, but since all geoglyphs are man-made, none can possibly be older than 100,000 years and my guess is that most of them are considerably younger. In addition to being younger than "millions of years", they are mostly in dry areas where they will be preserved better than they would be in, for example, a jungle.
