   A scientist determined a few decades ago that those pine trees have stood in the Pike Lakes region of Yakutat for thousands of years. Dorothy Peteet found an ancient needle in the bottom of a core she had pulled from the muskeg. She sent it to be carbon dated; the pine needle was about 10,000 years old.

   They examined the present range of lodgepole pine and decided that the tree could survive in interior Alaska if given a chance. Lodgepole pine grows from southern California to the Yukon, in environments varying from rainy seacoasts to dry inland mountaintops, because genetically different strains have developed.

   Outside, a steady stream of black bodies glided overhead, many of them swooping down to check me out. Their wings pushed the air in soft puffs as they continued past, 20 feet above the tops of wiry black spruce trees. As the sun set and the sky dimmed, the birds kept coming.

   Newcomers to Alaska will frequently order young pine, fruit or maple trees from their home state in the lower 48. They enthusiastically proclaim that the trees should do well here because the temperatures in Montana, or Minnesota, or North Dakota, or wherever they're from frequently plummet as low as they do in Alaska.

   Pine incense was used in religious ceremonies by the Aztecs, the Mayas, and the Romans. Pines were mentioned in Greek mythology. Greek scholars knew a great deal about pines, for these trees occupied a prominent place in the landscape. The oldest known living organism is a bristlecone pine found in California--it is over 5,000 years old.
