It can be tough even for die-hard fans of Twin Peaks to navigate its convoluted narrative. In the original 1990-1991 television series, the 1992 film (Twin Peaks: Fire Walk With Me), and the 2017 Showtime continuation (Twin Peaks: The Return), director David Lynch offered a sprawling examination of weirdness in a small town. Now fans have discovered Lynch has drawn a map, J.R.R. Tolkien-style, of his weird wonderland that helped his cast feel a little less lost.

Actor Kyle MacLachlan, who portrayed FBI Special Agent Dale Cooper on the show, posted Lynch’s hand-drawn map of Twin Peaks on Instagram.

“Two years ago, we made a journey back to a little town with some amazing Douglas Firs,” MacLachlan wrote. “Today I wanted to share a fun part of Twin Peaks history: to create a sense of place for the show, David Lynch drew this map of the town.”

Lynch is no stranger to illustration. In his career, he has worked in a variety of media including painting, drawing, sculptures, and anthropomorphic lamps. More than 500 of his pieces were on exhibit in Maastricht, the Netherlands recently, with another exhibit due to open in Manchester, England on July 6.
