for Scrub Peak, you see miles of nothing but Joshua Trees stretching out before you. This is on the west side of highway 91 and is looking towards Nevada. This is part of the Joshua Tree National Natural Landmark The Joshua Tree National Natural Landmark (aka Joshua Tree Natural Area) was designated on June 16, 1970. This natural landmark is incorporated in whole into the Joshua Tree Instant Sturdy Area (which was reviewed for Wilderness Characteristics). Natural Landmark status was given to this area because of the Joshua Tree vegetation association. The most dominant and dramatic of the plants in this association is the Joshua Tree (Yucca breviflora). At 1,015 acres, the Natural Landmark is but a small portion of the several thousand acre Joshua Tree Forest. It is the only Joshua Tree Forest in Utah and the northernmost significant stand of tree yuccas in the United States (some smaller, insignificant stands occur in Nevada near Tonopah and the Pahranagat Mountains).
