Description
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."

Treacherous Crevasses in Victoria Glacier, Canadian Rockies
Description
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."

Glacial boulder and glacial scratches, Bronx Park, New York
Description
Image Description from historic lecture booklet: "Many of the boulders and pebbles of the till are found to be glaciated, or marked with parallel scratches. Often they look as if engraved with a sharp need. Sometimes the scratches are deep and rough. A marked polish is seen on some stones. If we dig through the subsoil to the bed-rock, we shall often find the latter scratched in the same way, or even deeply grooved and carved into fluting's and the folding. The glacier, shod with stones at its base, drags these over the bed-rock, and thus both the moving fragments and the floor over which they move are polished and graven. The direction of the scratches corresponds to that in which the erratic boulders have been moved, and so, putting these other facts together, we have full proof that glaciers have done the work."
