Example text

According to some geologists, during mountain building times two large blocks of basement, metamorphic rock, broken along fault lines, were pushed up above surrounding rocks. The sedimentary layers that had been formed over the basement rock draped themselves like layers of blankets around the protruding blocks. When further mountain building occurred and the sedimentary layers were tilted, the dome protruded above the rest. A layer of very hard sandstone capped the top and east side of the dome, protecting the less resistant, reddish layers beneath; but on the west side these were exposed and subjected to extensive erosion.

Stout from Nebraska was put in charge. Stout supplanted Petra as the post office name, and the settlement even acquired a school. The quarry business flourished, and long trains carried away the sandstone. Nebraska's capitol and state penitentiary were built from some of it, and stone was also sent to Denver, Cheyenne, and Omaha. Quarrying continued steadily until the panic of 1893 but never completely recovered from that stoppage.

Pocket gophers abound on the tundra, working through the ground like small bulldozers and leaving piles of freshly worked soil here and there. " Alpine sunflowers, bluebells, and candytuft are especially likely to be clumped there. These gopher gardens tend to succumb to wind erosion, to be replaced by others. Even though Page 27 gophers have an enduring appetite for plants, they do tend to improve the diversity by their earth-moving activities.
