White House Ruins, Canyon de Chelly

White House Ruins, named for the white plastered room in the upper structure, is a ruin in Canyon de Chelly dating from the 11th century Anasazi culture. Plastered walls were common, but few have remained intact. This ruin originally reached to the ground, and stretched along the cliff wall, where up to 100 individuals might have lived, and the complex had room for 4-5 times that during ceremonial periods. The upper ruin would have been reached via the roofs of lower buildings and wooden ladders. Also of note is the large rock art figure below the upper ruins. It is not improbable that this pictograph would have originally been inside a room. Although this ruin can be reached from a canyon rim trail, everywhere else in Canyon de Chelly is closed to outsiders except Navajo and those being guided by Navajo.

Comb Ridge Panorama - Southern Utah

From National Geographic: 

Geologically speaking, the Comb is a monocline—a single fold in the Earth's crust created by a cataclysmic slippage of deeply buried tectonic plates some 65 million years ago. That upheaval has left a scar slashing across the desert landscape of the Southwest: a sharp ridge of sandstone that stretches almost 120 miles (193 kilometers) unbroken from just east of Kayenta, Arizona, to some ten miles (sixteen kilometers) west of Blanding, Utah.

The scale of the Comb is not colossal: Its ridgeline looms only from 300 to 900 feet (91 to 274 meters) above the plains, and shallow washes surround it on either side. But what the crest lacks in height, it makes up in ruggedness. No smooth arête, the ridge swoops to sharp summits and dips to V-notch cols with relentless regularity. To hike the Comb is to run a gauntlet of up-and-down severities, always at an ankle-wrenching, sideways pitch. There is not a single mile of established trail in the Comb's reach, which is one reason why no humans, to our knowledge, have ever traversed its length. We thought we should be the first.

Native American Woman on Horse with Travois and Child

This is an incredible image, that shows a Native American woman on a horse, pulling a travois and child.  There are not many other details in the image to suggest a time and place, other than the (relatively) modern building and corral in the background.  I image 1900's-1910's given the timeframe of other photos in this batch, but other than that it is anyone's guess.
