This photo looks eastward across the John Dellenback Dunes (south of Reedsport). While this picture
shows quite a bit of European beachgrass, the Dellenback dunes, overall, are quite pristine with little
vegetation. John Dellenback was a U.S. Congressman who played a key role in protecting the Oregon dunes
from development. He passed away in 2002. This section of dunes (some of the tallest and most beautiful
in Oregon) were named in his honor on May 8, 2004. Photo by Dina Pavlis, September 8, 2008.
Seasonal ponds are fantastic playgrounds for dogs and people on warm spring days. All of our ponds rise up from aquifers below the dunes
so they are filtered by sand. Many of them are crystal clear and some are deep enough for swimming. During a winter and spring of heavy
rain (like 2010), the ponds will remain into summer. Photo by Dina Pavlis, Oregon Dunes Day Use Area, March 14, 2010.
Sand extends into the forest (right side of photo), creating a parabola dune. Parabola dunes are created when sand pushes forward covering vegetation.
This movement of sand sometimes creates u-shaped dunes because the sand is surrounded on three sides by forest or vegetation. Parabola dunes are so
named because of their arc-like shape. Photo by Dina Pavlis, Oregon Dunes, July 11, 2010.
This picture shows a great example of why European beachgrass was introduced into our area to stop moving sand. Sand continually moves forward
with the summer wind, covering anything in its path (roads, rivers and jetties). In this photo, sand, unhindered, begins to cover a roadway.

During winter, water rises up from rain-soaked aquifers that lie beneath the dunes. In this photo, islands appear
where water has risen up around a pair of hummocks (small hills of sand). Photo by Dina Pavlis, South Jetty Dunes,

A trail of footprints gives evidence of a hiker long past. In summer, footprints are covered up quickly by moving sand, but in winter, when sand
is wet, heavy and still, footprints remain until rain washes them away. Photo by Dina Pavlis, Oregon Dunes near Florence, Oregon, December 8, 2007.
It is amazing how many different patterns are created in the sand by wind and rain. This photo shows at least
seven distinct patterns. Light-colored sand is not as heavy as the darker grains, so the colors are sorted by
the wind adding definition to these complex and beautiful patterns. Photo by Dina Pavlis, Oregon Dunes, September 6, 2010.
