Forest Service map prices will increase to $14 Jan. 1, according to a press release. The Forest Service continually updates its maps. The Forest Service expects to shorten the revision cycle as cartographers continue to apply new digital technology to the map revision process. Maps can be purchased at any of the Malheur National Forest offices or at NationalForestStore.com. The Forest Service is also working to increase the availability of digital maps. Digital maps for mobile applications can be downloaded at avenza.com/pdf-maps/store. Digital maps cost $4.99 per side.
