The land of form, the realm of music and of song--running, pouring, rushing, rhythmic waters; but preëminently a land of color: flowing red, yellow, orange, crimson and purplish, green and blue. Miles of black and white. This riot and regularity and vast distribution of color in continual change--it glows and is subdued with the shift of shadows, with the view-point of the sun. X LASSEN VOLCANIC NATIONAL PARK An active volcano is the imposing exhibit in the Lassen Volcanic National Park. The fiery Lassen Peak rises in the midst of telling volcanic records that have been made and changed through many thousand years. This Park is in northern California. It is about one hundred and fifty miles south of the Crater Lake National Park. The territory embraces the southern end of the Cascade Mountains, the northern end of the Sierra, and through it is the cross-connection between the Sierra and the Coast Range. The area is about one hundred and twenty-five square miles. The major portion of the Park lies at an altitude of between six thousand and eight thousand feet, the lowest part being about four thousand feet, while the highest point, the summit of Lassen Peak, is 10,437 feet above the level of the sea. The Park is reached by automobile roads. It is easily accessible from the Southern Pacific Railroad in the upper Sacramento Valley, and from the Western Pacific Railroad on the Feather River. The scientific and scenic merits of this territory were of such uncommon order that in 1907 they were reserved in the Mount Lassen and Cinder Cone National Monuments. Both these reservations are now merged into the Lassen Volcanic National Park. Lassen Peak is one of the great volcanoes of the Pacific Coast. Most of the material in it, and that of the surrounding territory, appears to be of volcanic origin. It is in the margin of one of the largest lava-fields in the world. The lava in this vast field extends northward through western Oregon and Washington and far eastward, including southern Idaho and the Yellowstone National Park. It has an area of about two hundred and fifty thousand square miles, over parts of which the lava is of great depth. Lassen is the southernmost fire mountain of that numerous group of volcanoes that have so greatly changed the surface of the Northwest. Among its conspicuous volcanic companions are Crater Lake, formerly Mount Mazama, Mount Hood, Mount St. Helens, Mount Baker, and Mount Rainier. Until Lassen Peak burst forth in 1914 it had slumbered for centuries, and was commonly considered extinct. It has probably been intermittently active for ages. Many geologists think that this activity has extended through not less than two million years. Just how long it may show its red tongue and its black clouds of breath is uncertain; and just how violent and how voluminous its eruptions may become are matters of conjecture.
