Psalms 104:8

This period also witnesses the end of the continental drift and the building of the modern mountains of Urantia. But the pressure of the continental masses and the thwarted momentum of their agelong drift are not the exclusive influences in mountain building. The chief and underlying factor in determining the location of a mountain range is the pre-existent lowland, or trough, which has become filled up with the comparatively lighter deposits of the land erosion and marine drifts of the preceding ages. These lighter areas of land are sometimes 15,000 to 20,000 feet thick; therefore, when the crust is subjected to pressure from any cause, these lighter areas are the first to crumple up, fold, and rise upward to afford compensatory adjustment for the contending and conflicting forces and pressures at work in the earth’s crust or underneath the crust. Sometimes these upthrusts of land occur without folding. But in connection with the rise of the Rocky Mountains, great folding and tilting occurred, coupled with enormous overthrusts of the various layers, both underground and at the surface.

For thousands of years after the submergence of the first Eden the mountains about the eastern coast of the Mediterranean and those to the northwest and northeast of Mesopotamia continued to rise. This elevation of the highlands was greatly accelerated about 5000 b.c., and this, together with greatly increased snowfall on the northern mountains, caused unprecedented floods each spring throughout the Euphrates valley. These spring floods grew increasingly worse so that eventually the inhabitants of the river regions were driven to the eastern highlands. For almost a thousand years scores of cities were practically deserted because of these extensive deluges.

You will raise me up to sit with you on the battlements on high.

Great troughs developed in North America, paralleling the Atlantic and Pacific coasts. The great eastern-Connecticut fault appeared, one side eventually sinking two miles. Many of these North American troughs were later filled with erosion deposits, as also were many of the basins of the fresh- and salt-water lakes of the mountain regions. Later on, these filled land depressions were greatly elevated by lava flows which occurred underground. The petrified forests of many regions belong to this epoch.

The earth’s early crust was highly unstable, but mountains were not in process of formation. The planet contracted under gravity pressure as it formed. Mountains are not the result of the collapse of the cooling crust of a contracting sphere; they appear later on as a result of the action of rain, gravity, and erosion.

When word had reached the dwellers in the land of the second garden that the king and high priest of the Garden of Eden was marching on them, they had fled in haste to the eastern mountains. Adam found all of the desired territory vacated when he arrived. And here in this new location Adam and his helpers set themselves to work to build new homes and establish a new center of culture and religion.

The present North American Rocky Mountain region is not the original elevation of land; that elevation had been long since leveled by erosion and then re-elevated. The present front range of mountains is what is left of the remains of the original range which was re-elevated. Pikes Peak and Longs Peak are outstanding examples of this mountain activity, extending over two or more generations of mountain lives. These two peaks held their heads above water during several of the preceding inundations.

In these early ages when much land was near sea level, there occurred many successive submergences and emergences. The earth’s crust was just entering upon its later period of comparative stabilization. The undulations, rises and dips, of the earlier continental drift contributed to the frequency of the periodic submergence of the great land masses.

Said Amos: “He who formed the mountains and created the wind, seek him who formed the seven stars and Orion, who turns the shadow of death into the morning and makes the day dark as night.” And in denouncing his half-religious, timeserving, and sometimes immoral fellows, he sought to portray the inexorable justice of an unchanging Yahweh when he said of the evildoers: “Though they dig into hell, thence shall I take them; though they climb up to heaven, thence will I bring them down.” “And though they go into captivity before their enemies, thence will I direct the sword of justice, and it shall slay them.” Amos further startled his hearers when, pointing a reproving and accusing finger at them, he declared in the name of Yahweh: “Surely I will never forget any of your works.” “And I will sift the house of Israel among all nations as wheat is sifted in a sieve.”

This period thus becomes the modern mountain-building stage of geologic history. Prior to this time there were few mountain peaks, merely elevated land ridges of great width. Now the Pacific coast range was beginning to elevate, but it was located seven hundred miles west of the present shore line. The Sierras were beginning to form, their gold-bearing quartz strata being the product of lava flows of this epoch. In the eastern part of North America, Atlantic sea pressure was also working to cause land elevation.
