Explore! Joshua Tree National Park

On page 20, in the first paragraph under Geography and Geology, the second sentence should read "Most North American mountain ranges trend generally north and south, but the several ranges that are encompassed in Joshua Tree National Park run east to west, as do the ranges to the west, the San Bernadino and San Gabriel Mountains." (The San Jacinto Mountains are part of a north-south range that extends into Baja California.)
