At the upper edge of this zone, at an elevation of probably seven thousand feet, beside some dashing stream or some clear pool, fed from the snows above, is the place for the camp. And such a camp! Oh, the beauty of such an unspoiled spot! [Illustration: On the Banks of the Columbia River, near Hood River. Photo. by E. H. Moorehouse.] It is from such a camp at the upper edge of the paradise zone that a party sets forth at the four o'clock hour to attain the highest. So the march on the great day of a final climb carries us at once into a fourth zone. This is the zone of avalanche and glacier, the zone of elemental fury and warfare, a zone of ever-steepening ascent, thirty degrees, a zone of almost winter cold at night, but with such a dazzling brightness and fervour in the day as turns the snow-banks to slush and sends the fountains tearing and cutting across the glaciers and triturating the moraines. Vegetation has now almost ceased, though the heather still drapes the ledges on the eastern or southern exposures, and occasionally one of the tenacious mountain pines upholds the banner of spring in some sheltered nook. This wind-swept and storm-lashed zone is also the zone of the wild goats and mountain sheep. On the precipitous ridges and along the narrow ledges at the margin of glaciers they can be seen bounding away at the approach of the party, sure-footed and swift at points where the nerve of the best human climber might fail. This zone carries the climbers to ten or eleven thousand feet of elevation on the highest peaks. And here is the place for the Mountaineers and Mazamas to take the half-hour rest on their arduous march. A sweet rest it is. We pick out some sheltered place on the eastern slope, and stretch ourselves at full length on the warm rocks, while the icy wind from the summit goes hurtling above us. And how good the chocolate and the malted milk and the prunes and raisins of the scanty lunch taste, while we rest and feel the might of elemental nature again fill our veins and lungs and hearts.
