Oregon Dunes

Oregon Dunes NRA https://www.fs.usda.gov/recarea/siuslaw/recreation/recarea/?recid=42465 https://en.wikipedia.org/wiki/Oregon_Dunes_National_Recreation_Area The Oregon Dunes National Recreation Area is located on the Oregon Coast, stretching approximately 40 miles (64 km) north of the Coos River in North Bend to the Siuslaw River in Florence, and adjoining Honeyman State Park on the west. It is part of Siuslaw National Forest. The Oregon Dunes are a unique area of windswept sand. They are the largest expanse of coastal sand dunes in North America and with some dunes reaching 500 feet (150 m) above sea level. There are about 7,000 acres (28 km2) of sand dunes, about a fifth of the total area of the national recreation area.

United States Department of Agriculture OREGON DUNES NATIONAL RECREATION AREA MAP & GUIDE Welcome to the Oregon Dunes National Recreation Area! In 1972 Congress recognized the unique value of the Oregon Dunes by designating the National Recreation Area to be managed by the U.S. Forest Service for “public outdoor recreation use and enjoyment by present and future generations, and the conservation of scenic, scientific, historic values…” Formed by the ancient forces of wind, water and time, these dunes are like no others in North America, and extend for 40 miles along the Oregon coast between Florence and Coos Bay. Wind sculpted dunes tower almost 500 feet above the ocean shore and blend with rivers, lakes and temperate rainforests to create a remarkably diverse ecosystem. Explore the largest expanse of coastal sand dunes in North America. Enjoy hiking through forests and dunes, riding an off-highway vehicle through a landscape of sand, or watching a sunset from a scenic beach. How about picnicking, camping, boating or fishing on one of the 30 lakes or rivers? Perhaps you’re a birder, beachcomber, berry or mushroom gatherer, or looking for accessibility? There are many opportunities to enjoy this special area. Please remember to share the responsibility of stewardship for this rare, ecologically complex, and beautiful national treasure.

Sand camps are sites are located directly on the sand, dispersed along the Oregon Dunes National Recreation Area. Camping access is by Off Highway Vehicle (OHV) on soft sand only and is allowed by reservation only through www.recreation.gov. Passes At some popular sites, a day-use fee may be required but many sites do not require fees. Recreation fees help maintain facilities and provide services. Day-use fees are $5 per vehicle per day. You can purchase your pass online at discovernw.org or on site (cash or check only). Other passes are also accepted. Popular passes include the $30 Northwest Forest Pass (good for 1 year for national forest sites in OR and WA), or the $80 America the Beautiful Annual Pass (good for 1 year for more than 2,000 Federal recreation sites.), and the $35 Oregon Pacific Coast Passport (good for 1 year at coastal Oregon State Parks and Federal sites). Other passes available include the Senior Pass (62+ older), Access Pass (permanent disability), Military Pass (current U.S. military members and dependents), and the 4th Grade Pass (free for 4th grade students).

For the grains of the Oregon Dunes, it has taken about 55 million years, starting with the building of the Coast and Cascade Mountain Ranges. Following the mountains’ formation, glaciers, rivers, wind, and rainfall began to grind these peaks down to tiny grains of sand and carry them to the ocean. There, currents push the sand onshore, where winds sculpt each grain into dunes. Wind Carves the Dunes The Foredune is a low hill parallel to the ocean. It exists because European beachgrass slows the wind, causing sand to drop out and pile up. Behind the foredune, the wind scours out the Deflation Plain all the way down to the water table and provides an area for plants to thrive. Summer winds carve wave patterns in the sand called Transverse Dunes. As the seasonal winds change direction, so do the patterns in the sand. At times the forest marches forward, other times the dunes smother the forest. Sometimes dunes leave pockets of forest, called Tree Islands, surrounded by sand. Oblique Dunes are the largest and most spectacular dunes, sometimes growing as tall as 180 feet and pushing inland 3 to 16 feet per year. Dune Invaders! European beachgrass was planted along the West Coast in the early 1900s to stabilize sandy coastlines and protect roads, water supplies, jetties, and homes. The grass thrived in its new environment. Beachgrass gains the upper hand The grass slowed the sand’s movement, and it piled up in a huge long foredune along the beach. Behind this dune, plants found a better place to grow. In just 50 years, huge mats of vegetation formed where there was once open sand. Now, plants and animals that need open sandy areas struggle to survive, and the open sand disappears from view. Land managers battle back European beachgrass is tough. It spreads quickly and thrives when buried under sand. Managers are exploring ways to control the grass, including hand-pulling, bulldozing, and spraying herbicides. Wh
