Your post made me go to a dusty corner of my shelves and take another long look at my dozen or so Ballentine paperbacks from the Sierra Club Exhibit Series. The books are rich in pictures, many by Elliot Porter, Philip Hyde, and earlier sources, with extensive documentation and west coast verse to support the photographs. All for $3.95 a copy! The dates and photo/editorial credits are frequently obscure but it seems they all appeared in the 1960s, under David Brower's editorship. And they must have printed boatloads, as they are still available used at single-digit prices. Dave Bohn's "Glacier Bay," had the greatest impact on me at the time. I ended up spending time there in a kayak a few years later. scott
