The shape of the Territory is regular, having the general form of a parallelogram, with its longer axis running east and west. Its relief is simple. Along the Pacific coast runs the Coast Range of mountains from the mouth of the Columbia River to the Straits of Juan de Fuca. In this range there is only one practicable opening from the interior, which is the trough of the Chehalis River, which terminates in Gray's Harbor. The bar here, as at the mouth of Columbia River, forms a serious obstruction to the entrance of vessels drawing more than twenty feet of water. Sixty miles east of the Coast Range, and parallel to it, runs the Cascade Range, which divides the Territory by a north and south line. It is a lofty range, presenting a serrated outline, whose lower depressions are 3,000 to 4,000 feet above tide, while summits of 5,000 to 8,000 feet are common; and at intervals still higher peaks raise their snow-covered heads from 8,000 to 14,500 feet. Between the Cascade Mountains and the Coast Range lies Puget Sound, with its outlet through the Strait of Fuca. South of this sound, and on each side, are wide spaces of flat and rolling country, with numerous and somewhat disconnected mountains of comparatively small size, though some of them rise as high as 1,500 feet. These mountains show many natural terraces, which may be the result of land-slides.

It has a broad outlet to the ocean. Lake Washington is a beautiful and navigable sheet of water. There are numerous other lakes scattered over the Territory, enlivening its scenery and often affording convenient waterways. Quite a number of the rivers emptying into Puget Sound are partially navigable for small steamers. The rivers and creeks generally have bottom-lands, which are sometimes narrow, and sometimes wide. Cowlitz River flows south into the Columbia River. It has fine bottom-lands, and its valley may be regarded as a prolongation and complement of the Willamette Valley, Oregon. [Sidenote: West Washington and East Washington.] All the country lying west of the crest-line of the Cascade Mountains is known as West Washington, and is quite different in topography, as in many other respects, from the country known as East Washington, which name applies to all of the Territory lying east of the Cascade axis.
