Forest Service Maps
Yes. On average, the Forest Service updates its maps every 2 to 7 years. For some maps where little change occurs, revision may not be scheduled for many years.
Trails and symbols are shown clearly. A comprehensive legend appears on each map. Since each map is unique, placement of the legend varies.
Forest Visitor Maps are at a smaller scale than USGS topographic quadrangle maps and typically do not show contours.
Forest Visitor Maps are best used to view an entire National Forest. They are great for driving through or planning a trip to the forest, showing recreational sites, campgrounds, public information sites and other attractions in the forest.
The Universal Transverse Mercator (UTM) grid is not used on the Forest Visitor map series owing to its small scale and intended use. The more detailed Wilderness and special area maps may have UTM grid ticks.
Currently, some Forest Service units have elected not to participate in the USGS distribution program. The USGS hopes to carry all Forest Service maps in the future.
