Three New Yorker-length articles (that's where they were first published) on the Atchafalaya River in Louisiana, Iceland's Heimay volcano, and the San Gabriel Mountains. His books are crying out for maps, but for some reason, he doesn't add any photos or maps (some drawings of Icelandic houses, which seem very tangential to the main story), fortunately, we live in the age of Googleearth, so I was able to find most (but not all) places he mentioned.
