The Wilson-Leonard site in Williamson County near Leander yielded unmistakable evidence of earth oven baking in the layer indicated by the white arrow. The visible rocks are fire-cracked cooking stones that formed several overlapping and jumbled earth oven beds dating to about 7,000 B.C. Amid the bones were fragments of charred wild hyacinth (Camas sp.) bulbs, a plant known to require prolonged baking before it is edible. TARL archives.
