Bruneau Dunes State Park
June 7, 2007.
We are staying at Three
Island Crossing State Park located in the town of Glynn's
Ferry. $4 entry fee plus $21 for RV site with water &
elect. Very nice campground and it is full. Mature trees with good
shade and green grass. If by chance the campground at Three
Island Crossing is full there is a nice commercial campground
at a winery located at the front gate to the State Park. They were
$20 for FHU and they had shade. Point being----they would be a good
alternative and some would like it better than the state park since
is was $1 cheaper and it had FHU.
After visiting Three
Island Crossing State Park the second place we wanted to experience
today was Bruneau
Dunes State Park. Bruneau Dunes
State Park just happens to be located 25-miles west of Three
Island Crossing. Driving there is an interesting drive along
the Snake
River and through a beautiful Snake
River Valley agricultural area.
Bruneau Dunes State Park is located
in an ancient Snake
River meander scar, known as Eagle Cove. The Snake
River plain is a broad trench extending approximately 300
miles across southern Idaho.
Volcanic activity was present for thousands of years. Lava
flows occasionally dammed the Snake
River canyon forming lakes which deposited large amounts of
sediment that have become part of the sand supply for the dunes.
Bruneau Dunes State Park is part
of the southern Idaho semi-arid
desert, a region of dramatic extremes, yet featuring a diverse range
of plant and animal life. This area of Idaho
averages only 7 inches of precipitation per year, with a normal summer
temperature in the 90's.
The dune field of Bruenau Dunes State Park
is not large as dune fields go. Bruneau
Dunes (Brueneau Dunes State Park
are located inside an old river meander scar surrounded by a much higher
mesa on all sides.

Dunes State Park dune field.
Eagle Cove makes a natural sand trap. Bruneau
Dunes started to form approximately 11,000 years ago after
the tremendous Bonneville flood. Bruneau
Dunes is the tallest single sand dune structure in North America.
Ideal conditions existed here for sand dune formation:
A circular basin, carved by the Snake
River, which forms a natural trap to catch wind-blown sand.
A supply of sand coming from ancient sediments laid down in the Snake
River Plateau.
A wind blowing at least 10 miles per-hour to transport the sand granules.
Grains of sand in this dune field are all about the same size. Smaller
sand continues on blowing while larger grains aren't moved by the
wind.
Bruneau Dunes is the tallest
single sand dune structure in North America.
