A contour about to cross a stream runs up one side and down the other, making a V where it crosses, the angle of the V pointing up stream. Contour lines representing spurs between stream lines are generally U shaped with the bottom or rounded part of the U pointing down hill.

"The sun is so far away that it would appear at the same angle from Philadelphia, St. Louis, and Denver, and if it were noon at one of these places, it would be noon at the others. Vertical lines at the three places would be parallel. But when it is noon at St. Louis, it is 1 P.M. at Philadelphia and 11 A.M. at Denver." -Dryer, 1901

"Lava has been forced not only into vertical cracks, but also between the layers of stratified rock, where it has hardened and forms more or less horizontal sills. In some instances the quantity of liquid rock forced into one locality is sufficient to raise the overlying strata into a dome which appears upon the surface of a mountain. Such accumulation of igenous material in the midst of sedimentary rocks are called laccolites." -Dryer, 1901

"At 1, a series of compressed folds has been worn down to a plain, the surface of which is formed by the edges of the nearly vertical strata. At 2 an anticline has been reduced to a valley, and at 3 a syncline is left standing as a ridge made up of concave strata like a pile of platters. The ridges at 4 are projections of hard strata above the more easily eroded ones on either side." -Dryer, 1901
