More pictures from Arizona. 跟多 Arizona 照片。

"Petrified wood (from the Greek root petro meaning "rock" or "stone"; literally "wood turned into stone") is a type of fossil that consists of fossil wood in which all the organic materials have been replaced with minerals (most often a silicate, such as quartz), while retaining the original structure of the wood. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen. Mineral-rich water flowing through the sediment deposits minerals in the plant's cells and as the plant's lignin and cellulose decay away, a stone mould forms in its place. In general, wood takes less than 100 years to petrify. The organic matter needs to become petrified before it decomposes completely. A forest where the wood has petrified becomes known as a petrified forest." ~Petrified Wood Wikipedia page.

"A cactus is (plural: cacti) a member of the plant family Cactaceae, native to the Americas (with one exception, Rhipsalis baccifera, which is native to parts of the Old World). They are often used as ornamental plants, and some are also crop plants for fodder, forage, fruits, cochineal, and other uses. Numerous species have been used since ancient times by indigenous peoples for their psychedelic effects. Cacti are part of the plant order Caryophyllales, which also includes members like beets, gypsophila, spinach, amaranth, tumbleweeds, carnations, rhubarb, buckwheat, plumbago, bougainvillea, chickweed and knotgrass." ~Wikipedia Page.
