In the magnificent forest around the cave entrance there are trails along which one gets inspiring views of forest-covered mountains and valleys. Along the trails one can observe many species of trees, mammals, and birds. Lava Beds National Monument Located in northeastern California, the monument includes an area of 45,000 acres. As the name suggests, volcanic formations, some of quite recent origin, are of greatest importance. There are hundreds of lava tubes which were once the passageways for streams of molten lava.
Volcanic cones rise above the general level of the adjacent country.
Within the monument there are interesting historical features including battlefields of the Modoc War of 1872-73. There are important ethnological and archaeological features. Petroglyphs on cliffs and pictographs in caves are evidence that the region was inhabited by primitive people long before the coming of the white man. Park Naturalist A combination of many features makes Crater Lake an outstanding scenic attraction as well as a most interesting and unique lake. John Wesley Hillman, the discoverer of Crater Lake, recorded in a description of the discovery that he and his companions were impressed with a number of features, among them, that the lake apparently had no inlet and no outlet.
