What strikes you about the examples of the art and culture of the indigenous peoples of the Americas that you see in those pages?

Note that the Anasazi seed jar (Figure 9.12) on page 254 and the gold ceremonial knife (Figure 9.13) on page 255 are both around a thousand years old. (See the Colossal Olmec head as well from Veracruz, Mexico (figure 1.34) that is three thousand years old.) What does that suggest about the cultures of the Americas?
