Though it distances all competitors in taking possession of fire-cleared territory, it is less successful than its fellows in entering a territory already occupied by other trees or by grass, because its seedlings cannot endure shade, and its seeds will not germinate or take root except they be brought directly into contact with clean mineral soil. The lodge-pole, therefore, needs the assistance of fire both to acquire and to hold territory. Increase the number of forest fires, and the lodge-pole extends its holdings; if we could stop fires altogether, the lodge-pole would become almost extinct. The lodge-pole has an astonishing altitudinal as well as latitudinal range. Scattered pretty well over the mountain region of the western United States, thence northward along the coast over much of the head-waters of the Yukon in Alaska, it occupies an enormous area. Over this it adapts itself with marked success to a variety of soil, moisture, and climatic conditions, and covers ragged tracts from warm sea-beaches to dry, cold mountain slopes eleven thousand feet above the sea. In many places it surrenders the traditional pole form of its race and wins success by becoming thick-barked, stocky, and limb-covered from top to bottom. Mountain Parks Mountain Parks The grassy park openings within the mountain forests are among the great charms of the outdoor world. These are as varied in their forms as clouds, delightfully irregular of outline. Their ragged-edged border of forest, with its grassy bays and peninsulas of trees, is a delight. Numbers are bordered by a lake or a crag, and many are crossed by brooks and decorated with scattered trees and tree-clumps. Others extend across swelling moraines. All are formed on Nature's free and flowing lines, have the charms of the irregular, and are model parks which many landscape gardeners have tried in vain to imitate. They vary in size from a mere grass-plot to a wide prairie within the forest.
