The Yosemite by John Muir — Read

Between the heavy pine and silver fir zones towers the Big Tree (_Sequoia gigantea_), the king of all the conifers in the world, "the noblest of the noble race. " The groves nearest Yosemite Valley are about twenty miles to the westward and southward and are called the Tuolumne, Merced and Mariposa groves. It extends, a widely interrupted belt, from a very small grove on the middle fork of the American River to the head of Deer Creek, a distance of about 260 miles, its northern limit being near the thirty-ninth parallel, the southern a little below the thirty-sixth. The elevation of the belt above the sea varies from about 5000 to 8000 feet. From the American River to Kings River the species occurs only in small isolated groups so sparsely distributed along the belt that three of the gaps in it are from forty to sixty miles wide.

But from Kings River south-ward the sequoia is not restricted to mere groves but extends across the wide rugged basins of the Kaweah and Tule Rivers in noble forests, a distance of nearly seventy miles, the continuity of this part of the belt being broken only by the main cañons. The Fresno, the largest of the northern groves, has an area of three or four square miles, a short distance to the southward of the famous Mariposa grove. Along the south rim of the cañon of the south fork of Kings River there is a majestic sequoia forest about six miles long by two wide. This is the northernmost group that may fairly be called a forest. Descending the divide between the Kings and Kaweah Rivers you come to the grand forests that form the main continuous portion of the belt. Southward the giants become more and more irrepressibly exuberant, heaving their massive crowns into the sky from every ridge and slope, waving onward in graceful compliance with the complicated topography of the region. The finest of the Kaweah section of the belt is on the broad ridge between Marble Creek and the middle fork, and is called the Giant Forest. It extends from the granite headlands, overlooking the hot San Joaquin plains, to within a few miles of the cool glacial fountains of the summit peaks. The extreme upper limit of the belt is reached between the middle and south forks of the Kaweah at a height of 8400 feet, but the finest block of big tree forests in the entire belt is on the north fork of Tule River, and is included in the Sequoia National Park.
