ANTIQUES ROADSHOW continues its visit to Albuquerque, where just outside the city limits, host Dan Elias finds himself exploring the New Mexico of other millennia. At Petroglyph National Park, images carved in rock are evidence of Pueblo Indian life as early as 1000 B.C., while dinosaur fossil remains at Ghost Ranch date back hundreds of millions of years. Back in the 21st century, appraisers at the Albuquerque Convention Center examine the more recent past: a post-Revolutionary War canteen accompanied by a diary account of the Revolution written by the owner's great-great-great-great-grandfather, a member of the Massachusetts Militia -- an original 1908 illustration by Arthur Rackham, perhaps the most celebrated British children's book illustrator -- and a luscious, pear-shaped pear-wood tea caddy valued at $7,000 to $8,000.
