The timber and waterway network of Mason County is clearly visible on this 1981 survey, where logging infrastructure meets the natural flow of the Middle Fork Satsop River. The small settlement of Matlock serves as a focal point, connected to the surrounding woods by a railroad that includes features such as the Frisken Wye and Matlock (Siding). This rail system underscores the era's reliance on fixed transport for the local logging industry.
