Lord, Nancy, Beluga Days: Tracking the Endangered White Whale. Mountaineers. Softbound. 239 pages plus notes. Three maps. $16.95.

The beluga whales of Cook Inlet are endangered. That is the one thing everyone can agree on. There are now fewer than only twenty years ago. That is where the agreement stops. How many fewer? Enough to list them as heading for extinction or enough to put them on a watch list? Is the cause over-hunting or is it pollution from the oil rigs in the inlet? How about pollution coming down from Anchorage and the towns along the inlet? There is at least one chemical plant nearby, not to mention the oil and gas washed off the roads and into the bays.
