"Living for more than five thousand years, ancient bristlecone pines are the oldest trees on Earth. Recorded in their rings are 'secrets' -- scientific evidence of a changing planet. A volcano erupts in 2036 BC. In 777, a storm explodes on the sun. Lightning strikes in 1122. And during the 20th century, the temperature increases dramatically. What is the secret to the bristlecone's exceptionally long life? Alexandra Siy's lyrical text, paired with Marlo Garnsworthy's meticulously researched mixed media painting, reveals the life cycle of the mysterious ancient bristlecone pine." -- Back cover.
