This National Park is a relatively newly developed scenic spot, relatively cold. Located on the east side of Los Angeles by Palm Spring. It covers a large area, but most of the park is desert. We enter from the Northeast gate of the park and then exit from the West gate, which is about a fifth of the area. The largest number of stones in the park, except deserts, are said to have sunk under the ocean many years ago, because of crustal movement. Because of these rocky mountains, it is also a paradise for rock climbers. Almost every rock climber is brave. We have annual tickets for national parks, so we don't know how much they cost, but they should be inexpensive. The Joshua tree is a kind of tree in this park, but we don't know which kind of tree it is.
