A burl is a dense, knotty outgrowth from a tree, a type of callus tissue formed in response to damage (like fire, insect, or fungal attacks) or environmental stress. Although a burl is a form of tree damage, it looks like an interesting natural design.

Designs in a Rock
This rock is naturally formed, creating designs. Â Often, those white bands or stripes, called veins, are quartz or calcite. Quartz filled the fissures and cracks in rocks. The calcite was formed from the precipitation of calcium carbonate from water running over and through the rocks.
