In the manner of Woodpile (1990), still another observation of a particular site, presumably on his Maine farm, by this much- honored illustrator. With his trademark bits of telling detail, spare, angular line, and muted color against dramaticly expansive white, Parnall records the changes--swift and slow, within, upon, and around--a large rock that plays host to various plants and creatures. A lovely tribute to nature's orderly, thrifty ways. (Picture book. 5-10)
