SCIENCE FILE / An exploration of issues and trends affecting science, medicine and the environment

February 01, 1996|NONA YATES

When describing Alaska's Tongass National Forest, superlatives abound. It is: the largest national forest (17 million acres), the most extensive single concentration of virgin forest left in existence, home to a glacier larger than Rhode Island, old-growth stands of hemlock, cedar and Sitka spruce up to 5,000 years old, and North America's highest concentration of grizzly bears, according to the museum. It also is a focal point for controversy between timber interests and environmentalists over logging practices such as clear-cutting.

An exhibition of photographs detailing the lush land and abundant wildlife of the Tongass will be on display at the Natural History Museum of Los Angeles County through March 31. Call (213) 744-DINO.
