Sep 16, 2014 -- Several of the 1,835 new US Topo quadrangles for the state now display parts of the Trail along with other improved data layers.
“Having the Pacific Crest NST finally show up on Oregon US Topo maps is significant for all of the recreational users of the wild spaces the trail traverses,” said Tom Carlson, Geospatial Liaison for the Pacific Northwest. “Hiking the trail provides commanding views of the volcanic peaks of the Cascade Range as well as the verdant forests of the western side of the mountains and down into the farmlands of the Willamette Valley. You also see parts of the open Ponderosa Pine forest and high desert on the eastern slopes of the mountains.”
The Pacific Crest National Scenic Trail is a treasured pathway through some of the most scenic terrain in the nation. Beginning in southern California at the Mexican border, the PCT travels a total distance of 2,650 miles through California, Oregon, and Washington until reaching the Canadian border. The PCT is one of the original National Scenic Trails established by Congress in the 1968 National Trails System Act and fifty-four percent of the trail lies within designated wilderness.
The USGS partnered with the U.S. Forest Service to incorporate the trail onto the Oregon US Topo maps. This NST joins the Ice Age National Scenic Trail, the Pacific Northwest National Scenic Trail and the North Country National Scenic Trail as being featured on the new US Topo quads. The USGS hopes to eventually include all National Scenic Trails in The National Map products.
Another important addition to the new Oregon US Topo maps in the inclusion of Public Land Survey System. PLSS is a way of subdividing and describing land in the US. All lands in the public domain are subject to subdivision by this rectangular system of surveys, which is regulated by the U.S. Department of the Interior.

Figure 1 - The National Trails System was established by Act of Congress in 1968. The Act grants the Secretary of Interior and the Secretary of Agriculture authority over the National Trails System. The Act defines four types of trails. Two of these types, the National Historic Trails and National Scenic Trails, can only be designated by Act of Congress. National scenic trails are extended trails located as to provide for maximum outdoor recreation potential and for the conservation and enjoyment of nationally significant scenic, historic, natural, and cultural qualities of the area through which such trails may pass.
There are 11 National Scenic Trails:
- Appalachian National Scenic Trail
- Pacific Crest National Scenic Trail
- Continental Divide National Scenic Trail
- North Country National Scenic Trail
- Ice Age National Scenic Trail
- Potomac Heritage National Scenic Trail
- Natchez Trace National Scenic Trail
- Florida National Scenic Trail
- Arizona National Scenic Trail
- New England National Scenic Trail
- Pacific Northwest National Scenic Trail
