Houses in the country are not connected to a city sewage system so each household installs a septic tank. It is a large tank made of concrete, plastic, or fiberglass that is buried in the ground. Sewer lines from the house empty into it. Over a period of years, the tank sometimes fills up and water flows out of it, forming a pool in a low spot. They can also be found hanging around the canyon rims.
Buzzards are carrion eaters which means that they live on dead animals.
The contents of a buzzard's stomach is almost beyond description. If anyone or anything ever gets close enough to a buzzard to alarm him, he will show you the contents of his latest meal. As you might guess, buzzards don't have many natural enemies. Wallace tells the coyotes to leave, and when they don't, he unloads on them. The discarded scrap metal around the machine shed is a great place for rattlesnakes to hide.
