THE NATIONAL GEOGRAPHIC MAGAZINE Photograph by Frederick U. Vosburgh OLD FAITHFUL'S THREE-FOOT THROAT: THE "BUMPS" BETRAY HER AGE Between eruptions, a ranger on the twenty-foot-high cone rests his hand on the sinter-covered stump of a pine. Recent discovery that trees grew here, in a spot now deluged hourly in 10,000 gallons of scalding water, indicates that the geyser is much younger than supposed (page 772 and Plate I). Photograph by Edwin L. Wisherd A PAIR OF PEDALING SCHOOLTEACHERS "CROSS THE GREAT DIVIDE" They shipped their "bikes" and themselves to the park by train, then roamed in quiet, rubber-tired leisure from one end to the other. Here they pause at Isa Lake, which drains to both Atlantic and Pacific.
