The Western United States: A Geographical Reader

by Harold W. Fairbanks

It was soon discovered that the Hudson was a short river and did not lead across the continent as was at first hoped. Because of the absence of other large rivers upon that portion of the coast which the English occupied, their settlements did not spread westward as rapidly as they otherwise would have done. The country was covered with dense forests, and savage Indians disputed the right to occupy it. In time, however, passes were found leading over the Appalachian Mountains to the Ohio River and through the Mohawk Valley to the region of the Great Lakes.

The advantages for travel offered by the St. Lawrence River and the chain of lakes above it were utilized at an early day. The route of the French missionary explorers and fur traders was from Montreal up the Ottawa River, then by a short portage and a series of small lakes to Lake Huron. From this point the most remote shores of Lakes Superior and Michigan could be easily reached. By the aid of several small bodies of water west of Lake Superior, Lake Winnipeg and Great Slave Lake were finally discovered; but from this point the waterways into the West were small and could be followed no farther, so that it was a long time before the Rocky Mountains were crossed.

By floating down the Illinois River the French arrived at the Mississippi, explored much of its course, and took possession of the country in advance of the English. This fact was directly due to the difficulties which the English explorers experienced in forcing their way over the Appalachian highlands.

The Spanish explored the southern shores of the continent, and crossing the Isthmus, were the first to behold the Pacific. The fact that the Pacific coast of North America was so easily reached at this point gave the Spanish a great advantage, and explains why they gained such a hold upon the lands bordering that ocean. It was a comparatively simple matter for them to fit out ships, and sailing north and south, to take possession wherever they desired. However, when they had gone as far as California, their progress was for a long time almost completely blocked by storms and head winds, for the prevailing direction of the wind is down the coast. The Spanish finally reached Vancouver Island, but never succeeded in making settlements north of San Francisco. Even the interior of California was little known to them, for the mountains and deserts discouraged their progress in that direction.

From an examination of a map we might suppose that the Colorado River would offer as good a means for penetrating the continent as did the Mississippi River, but as a matter of fact it is navigable for a comparatively short distance. The Spanish made one attempt to ascend this river, but finding themselves surrounded on every hand by a most desolate, barren country, they turned back before reaching the Grand Cañon. In the eager search for gold the Spaniards pushed north from Mexico and planted settlements in Arizona and New Mexico, but upon the northwest their progress was stopped by cañons and deserts.

Now we are prepared to understand why it was that the western portion of North America remained for so long a time a mysterious and unknown region. There were no waterways by which it could be explored, while snow-clad mountains and deserts made access to it doubly difficult.

By the beginning of the last century the Americans had overcome the natural obstacles in their westward progress, and their settlements reached as far into the wilderness as the Mississippi River. Hunters and traders were soon pushing far beyond, spreading over the Great Plains and up to the very base of the Rocky, or Stony Mountains, as they were then called. The Missouri River became the great highway into the Northwest, for the adventurers took advantage of the streams wherever possible. Many other rivers were discovered flowing from the western mountains, but with the exception of the Platte and Arkansas they were generally too shallow for navigation even with a light canoe.

Starting in the early spring from the mouth of the Missouri, the hardy trappers sailed and paddled up the river, taking several months to reach the head of navigation at the Great Falls. In the autumn, when the boats were loaded with furs, it was a comparatively easy matter to drop down the river with the current. It would have been almost impossible to transport the loads of goods on pack-horses across the thousand miles of prairie, where the traders would be subject to attack from hostile Indians.

Adventurous men pushed farther and farther west through the passes in the mountains and began trapping upon the waters which flow into the Pacific. It had long been supposed that the Rocky Mountains formed a barrier beyond which our country could not be extended, and that the Pacific slope was made up of mountains and deserts not worth securing.

The explorers showed that the Rocky Mountains were not continuous, but consisted of partly detached ranges, and that while their eastern fronts were indeed almost impassable for long distances, there were places so low that it was difficult to locate the exact spot where the waters parted to seek the Pacific Ocean and the Gulf of Mexico. In southwestern Wyoming the continental divide, known as the Great Divide mesa, though more than a mile above the sea, is but a continuation of the long, gentle slope of the Great Plains.
