The lowest elevations in Yosemite are found on the western boundary of the park at the El Portal Administrative Site, which is at approximately 1,800 feet (549 m). This is the foothill-woodland zone, an area that is hot and dry in the summer with very little or no snow in the winter. Plants within this zone include chamise, ceanothus, manzanita, blue oak, interior live oak, and gray pine. These plant communities can also be found near Hetch Hetchy reservoir.
