Ann Johnston’s six-year project making large quilts about the geology, gold rush, and landscape of the Sierra Nevada in California is described in this 146 page book. The gallery section includes 31 pieces with overall views, many of the backs, and close up details. The inspiration and process sections, over 62 pages, show the sources of her ideas and the processes involved in dyeing the fabric, assembling the pieces and quilting the designs. The text throughout is concise and informative, telling a personal story as well as one of geologic events.
