The Blackfoot Indians

More than 1,400 Walter McClintock glass lantern slides at the Yale Collection of Western Americana, Beinecke Rare Book and Manuscript Library.

"Pittsburgh native Walter McClintock graduated from Yale in 1891. In 1896 he traveled west as a photographer for a federal commission investigating national forests. McClintock became friends with the expedition’s Blackfoot Indian scout, William Jackson or Siksikakoan. When the commission completed its field work, Jackson introduced McClintock to the Blackfoot community of northwestern Montana. Over the next twenty years, supported by the Blackfoot elder Mad Wolf, McClintock made several thousand photographs of the Blackfoot, their homelands, their material culture, and their ceremonies. Like his contemporary, the photographer Edward Curtis, McClintock believed that Indian communities were undergoing swift, dramatic transformations that might obliterate their traditional culture. He sought to create a record of a life-way that might disappear. He wrote books, mounted photographic exhibitions, and delivered numerous public lectures about the Blackfoot."

Birch Bark Sauna

Birch bark has been used in Finland for centuries as a construction material and as material for making small objects like baskets and shoes. One of birch bark's features is good thermal insulation. The surface is water repellent and it can be gently washed with water. Some components of birch bark also protect it from decomposing.

Finnish architects Teija Losoi, Anne Varsamäki and Ilari Pirttilahti used the technique to build a lightweight sauna - basically a huge traditional birch bark basket turned upside down. The light walls are supported by a wooden structure that is hidden inside two layers of braided birch bark. More pictures: 1 / 2 / 3 / 4. Thank you, Zeltia !

Why Older Buildings are More Sustainable

"In the late 14th century, England's King Richard II commissioned a new building, College Hall, at Oxford University. The carpenters who built College Hall knew that the massive oak beams spanning the great hall's ceiling would probably need to be replaced in a few hundred years, so next to the building, they planted a row of oak seedlings from the trees they used for the beams. Sure enough, the beams needed to be replaced about 300 years later, and the new carpenters had mature oaks right there, ready to be milled and turned into new beams."

Greening Main Street Buildings (more). The picture shows an example of a recessed entryway - a characteristic common to many traditional commercial buildings that helps prevent hot or cold air from rushing inside when a door is opened.
