Image Description from historic lecture booklet: "Mendoza is one of the most important inland cities. Here, by means of irrigation, the people have cultivated large vineyards, and a great deal of win is made."
Image Description from historic lecture booklet: "When the amount of ice developed form snow becomes great enough, it begins to move out by a sort of spreading motion from the place where it was formed. When it begins to move, it becomes a glacier. Not all snow-fields give rise to glaciers, but all glaciers have their sources in snow-fields. For convenience of reference the glaciers now known may be arranged in three classes, alpine, piedmont, and continental. These three classes are not always distinct and clearly separable, but typical examples of each may be selected that are well characterized, and differ in essential features from typical examples of each of the other classes. In each group there are conspicuous variations which suggest minor or more specific subdivisions."
Image Description from historic lecture booklet: "Although ice under steady pressure slowly flows, when subjected to a decided strain it breaks, forming cracks, or crevasses in the glacier. Where the valley bottom is irregular, causing many steams in the moving ice, crevasses are especially abundant; and when the slope of the bottom is steep, the ice may become so crevassed that it is almost impossible to pass over it."
Image Description from historic lecture booklet: "This great mountain has an immense sheet of white granular ice divided up by the general jutting up of the rock masses or shoulders of the mountain into the Nisqually, Cowlitz, and White River glaciers, falling in distinct ice cascades for about 3000 feet at very steep angles which sometimes approach the perpendicular."
Image Description from historic lecture booklet: "The Illecellewaet glacier. This is an inherited basin glacier, in which the inherited topography has exercised a greater influence upon the glacier form than has the auto-sculpture."
