An outside photograph of a Native American man identified as Uma-Som-Kin. He is dressed in full regalia and sitting on a horse, next to a river. For his headdress, the man is wearing a bonnet with a single trail of eagle feathers. He is wearing a coat made out of a Pendleton blanket. He is wearing leggings with a design on the cuff and beaded moccasins. Because no stirrups can be seen, it would appear that he is riding either bareback or using a blanket for a saddle. He is holding the horse's bridle in both hands. The horse has a spotted coat. Across the river, on the opposite bank, are two cottonwood trees. In the background are rolling hills.
A group of adults and children, identified as instructors and pupils of the Umatilla Indian School, are performing farm work. A group of children are hanging out of a window of a barn. Six horses are yoked to two wagons.
An outside photograph of two men: one is a Euro-American and the other a Native American. Both men are standing in front of a multi-layered tule mat tipi. The photographer has identified the Native American man as Poker Jim. He is wearing a cowboy hat and is wrapped in a Pendleton blanket that reaches his ankles. He is holding the reins of a barebacked horse. The Euro-American is wearing a suit and overcoat and has both hands in his coat pockets. He also is wearing a derby hat. There are six visible external poles leaning against the tipi, presumably to hold down the woven mats. To the men's right, leaning against the tipi, is a homemade ladder that appears to be made of similar poles. The background shows a hint of hillside, along with cottonwood trees and a lone pine tree. At the base of the pine tree is a stack of firewood.

No Shirt's wife has her hair in braids and is wearing a hat. She is attired in a beaded buckskin dress and has a shawl over her lap. The shawl may be a Pendleton shawl. She is holding her horse reins and a cornhusk bag in her left hand, with her right hand resting on the bag. She is sitting on two saddle blankets. Her horse's coat is spotted. For his headdress, No Shirt is wearing a single trail bonnet with a set of horns on the bonnet and ermines that hang over his shoulders. He is wearing a choker around his neck and a fur bandoleer across his chest. He is holding horse reins in his left hand, and an unidentifiable object tipped with feathers in his right hand. His horse has a dark coat and is wearing what has been identified as a beaded martingale. In the photograph's background can be seen several tipis, the silhouette of other horses, and a rising hillside.
A group of three Native American women and a Native American man pose on horseback in front of a canvas tipi. Around the tipi are deciduous trees and shrubs with leaves; in the distance is a hill with scattered groves of trees or bushes. Two of the horses are white and two are dark. The man wears a broad-brimmed hat, cloth shirt and pants, a dark vest with a badge on it resembling the tribal police badges, a bandanna around his neck, and a choker necklace. His feet are in metal stirrups. He appears to have a gun or knife at his waist. The women all wear cloth scarves or sunbonnets which tie under their chins. They are all wearing cloth dresses with patterns: plaid, striped, floral. The woman in the middle has a blanket over her legs. The woman on the right is riding sidesaddle.

Outside photograph of a homestead in the mountains. A woman and child dressed in European-American clothing stand outside the door of a log cabin. Two men, also dressed in European-American clothing, stand in the back of a horse-drawn wagon. The cabin is at the base of a hill and is flanked by a tall pine tree on either side. In the foreground of the picture is a small wooden structure with a sloped roof; the structure is approximately two feet tall and might be used for storage. The hillside directly behind the cabin has been mostly cleared of trees but other trees are visible farther away. Under the eaves of the cabin is a ledge on which are stored a number of items, including a barrel. Other items are on the ground against the front of the cabin. Next to one of the trees is an apparatus that might be a circular saw.
A Native American man wearing regalia stands beside a horse. The man wears a feathered headdress, buckskin shirt, leggings, breechcloth, gloves, and necklaces. The horse is outfitted with a bridle that includes an ornament that is positioned over the horse's forehead.
Six men and eight horses are seen in the process of clearing land to form an irrigation canal or drainage ditch. One man sits on the hillside; the other men stand facing the camera. All the men are dressed in European-American clothing and all wear hats or caps. Two of the men are dressed in clothing that seems to be some sort of uniform, with square caps; they are also wearing high boots. The other men have wide-brimmed hats and they are wearing work clothes. The horses are hitched to some kind of apparatus that is not clearly visible.
A Native American man identified as "Young Chief" stands in profile, facing left, next to a dark-colored horse, in front of three tipis. Behind the tipis are trees with leaves on them. The horse wears a martingale with geometric beading, a saddle, and a beaded bridle. There seems to be a fringed rifle scabbard in front of the saddle, and a staff with feathers thrust into the ground between the horse and man. The man wears a single trail bonnet with ermine which seems to be slightly longer than he is tall. His dark hair hangs down in front in two braids. He wears a light-colored cloth shirt, the rounded tails of which hang below a short vest, and leggings. His left hand supports the base of a handle of a tomahawk, and a fur bandoleer. His right hand grips the top of the blade of the axe. Horse and man are facing into the sun; their shadows stretch behind them to the right of the photograph. A figure can be dimly seen through the triangular door of the tipi in the background., Young Chief—Cayuse Tribe [Young Chief, Cayuse man, in eagle bonnet with weapons.
