How did Jim describe the pastures when he returned to Black Hawk?

From the text:

I took a long walk north of the town, out into the pastures where the land was so rough that it had never been ploughed up, and the long red grass of early times still grew shaggy over the draws and hillocks. Out there I felt at home again. Overhead the sky was that indescribable blue of autumn; bright and shadowless, hard as enamel. To the south I could see the dun-shaded river bluffs that used to look so big to me, and all about stretched drying cornfields, of the pale-gold colour, I remembered so well. Russian thistles were blowing across the uplands and piling against the wire fences like barricades. Along the cattle-paths the plumes of goldenrod were already fading into sun-warmed velvet, grey with gold threads in it.
