Knife River Indian Villages
National Historical Site
North Dakota
by Shawn Salley
Introduction
Villages of Hidatsa and Mandan Indians are preserved at the Knife River Indian
Villages National Historical Site. The National Historic Site, which was
established in 1974, preserves the historic and archaeological remnants of the
Northern Plains Indians. At these villages Lewis and Clark obtained the
services of Sakakawea (Sacagawea) and her husband, Charbonneau, for there
journey to the west coast. The Awatixa Hidatsa Village, which is now being
eroded by the Knife River in the center of the park, is thought to be the
original home of Sakakawea.

mounds built up with earth along the sides and the roof. George Catlin, 1837-39,

The current remnants of the earth lodge structures are seen as depressions in
the ground. These, however, are not depressions carved into the ground. The
center of the lodge was once at ground level, and after the lodge was
abandoned, the surrounding dirt collapsed from the lodge walls and roof to create
the rim of the depressions. The circular features measure up to 12 meters
(40 feet) in diameter.

Large Format Images
Conventional Aerial Photography, or large format aerial photography, is acquired
at high altitudes. The images analyzed are Digital Orthophoto Quadrangles
(DOQ)
from the United States Geological Survey (USGS) and
QuickBird imagery from DigitalGlobe.
DOQ's are taken every 10 years through the USGS. This type of aerial photography
is computer generated imagery that removes displacement from camera tilt
and terrain relief. It combines qualities of the original photograph
with a geo-referenced map. The QuickBird data is satellite imagery which
records high-resolution data in the visible and near-infrared range.
The QuickBird satellite photos are acquired using the Google Maps search
engine.

this photo, the two villages closest to the visitors
center are visible. Notice the pitted appearance of the earth lodges in and outside the
mowed portions.

Village, 3- Awatixa Village (Sakakawea Site), 4 - Knife River. |

thought to be Sakakawea's village. Notice how the Knife
River is eroding into the village site. |

north of the Awatixa and Awatixa Xi'e Sites. Notice several more earth
lodges outside of the mowed path. |

Kite Aerial Photography
During an early autumn day in October 2003, we visited the Knife River Indian
Villages to conduct Small Format Aerial Photography. A sunny sky with a southern
wind created favorable conditions for utilizing kite aerial photography (KAP).
At two sites, the Awatixa Village and the Big Hidatsa Village, KAP was conducted
to document the fall conditions at this archeological site. The time of the year
allowed for an optimal viewing of the vegetative differences. The depressions
allow the different vegetation to be active during autumn conditions, showing the earth lodges with good detail. The field crew
included Shawn Salley, Dr. James Aber, and Billy Jacobson.

south to the Awatixa Xi'e village and the visitors center. Circular patterns in
the vegetation show many lodges between the two sites in the unmowed area. |

is seen to the lower left. |

A vertical shot of the Awatixa site shows how Knife River has eroded into
the village destroying a portion of the village. Part of the park's management
program is to minimize the erosion of the villages. |

building. This is the largest maintained area of this historical site.
The lodge structures are between 30 and 40 feet across. |

An eastern view of the Big Hidatsa Village shows multiple lodges that are not
in the maintained area. The small white patches in this area are animal burrows
(squirrels and gophers). |

Aerial Mosaics
Utilizing the computer software D Joiner
to merge the kite aerial photography, a mosaic of the
Big Hidatsa Village was constructed. This mosaic can be used to see the village
as a whole. The views from this mosaic maintains the high
detail from KAP while allowing a complete view of
the site. Other methods of acquiring these same views would require the
cost of using airplanes and large format photography.

of the Big Hidatsa Village looking south toward the maintenance building. The
scale is more accurate around the maintained village site, yet the view
becomes distorted towards the margins. The fragmented border is due to the absence
of data. Image processed by S. W. Salley ©, 4/05 |

above this area, it is an accurate spatial representation of the village. After
geo-referencing the image, an accurate scale is obtained. Image

Discussion
Visible remains of earth-lodge dwellings, cache pits, fortification
ditches, and travois trails are preserved in extraordinary condition at
the Knife River Indian Villages National Historical Site.
The most notable feature of the park is the remnants of the earth lodge
dwellings. Kite aerial photography allows an extraordinary view of these
historic sites. Utilizing joining software to mosaic the imagery, an
aerial perspective of
the whole site can be obtained at minimal costs. With the use of kites, small format aerial photography provides a useful tool to visualize the spatial aspects of this
important archeological site.
