Amazing that rocks could stay stacked for thousands of years where the natives are known for destroying things.

Above is one of the round "rooms" found by the Desert Team where the lines of "kites" intersect. In the background, you can also see one of the low lines that extends from this "room."

Below is a good image showing how low the lines are.

In my opinion this image shows a 4-legged animal crossing from right to left and overlapping the largest gate. They call this glyph a "kite."

Also, it is not a gate. It is a door. You unlock this door with the key of imagination. Beyond it is another dimension - a dimension of sound, a dimension of sight, a dimension of mind. You're moving into a land of both shadow and substance, of things and ideas. You've just crossed over into... the Twilight Zone.
