FRONTISPIECE.—Tahoma Glacier, shown here at left center of the photograph, cascades down the west slope of Mount Rainier where it forms the headwaters of South Puyallup River. South Tahoma Glacier rises on the side of Mount Rainier to the right, flows around a bedrock hill and terminates in a gray tongue of ice from which Tahoma Creek flows off to the right. The bare valley bottoms just below the termini were covered by the glaciers less than 60 years ago. (Photograph taken from Gobbler's Knob, September 20, 1967.)

FIGURE

1. Photograph—Samples from larger trees can be taken no closer than 2-3 feet above the ground; Sketch—Each annual ring is an elongated cone

2—8 Photographs:

2. Trees are sampled at the lowest possible level
3. South Tahoma Glacier and Tahoma Glacier joined in 1910 below Glacier Island
4. Junction of Tahoma Creek Trail and Wonderland Trail
5. The 1835—50 lateral moraine of South Tahoma Glacier
