This interesting formation is known as the Petrified Forest. "It is actually a collection of hollow tubes of limestone called "solution pipes", eroded by millions of years of rainfall. The process starts when water gathers in a shallow pan of sand and seeps downwards dissolving the limestone. The mineral-saturated water then cements the sand, forming hard, trunk-shaped pipes".
