The agave has a rosette arrangement of thick, fleshy succulent leaves with spiny edges and ending in a point. A tall stem grows from the center and flowers at the top. Once the flower goes to seed, the rosette dies.
Native Americans made and used roasting pits to cook various foods such as agave hearts. Roasting pits are circular areas of limestone. Their size varies from ground level circles five to six feet in diameter, to enormous piles several yards high and large sloping sides.
Limestone was gathered and heated by fire, then used to cook food. After prolonged use, the broken limestone was raked aside and replaced with new rocks. This caused the circle of rocks to grow with use.
