Glen Helen Regional Park is the site of California Historical Landmark NO. 573 Sycamore Grove, designation given on April 1, 1957. Its location is at Glen Helen Regional Park, 2555 Devore Rd, 0.7 mi W of Devore. Sycamore Grove was the first rest stop after the old Native American Mohave Trail left the West Fork Mojave River, following the trail, to cross the San Bernardino Mountains at Monument Peak, descending into Cajon Canyon on the ridge between Cable Canyon and Devil Canyon. This route was used by Father Francisco Garcés in March 1776 and Jedediah Smith in 1826. Sycamore Grove, named by the 1851 Mormon colonists, later called Martin's Ranch, Sycamore Valley Ranch, and Glen Helen Ranch, was a rest and water spot at the bottom of Cajon Pass on the Old Spanish Trail mentioned as a camp in the itinerary of Antonio Armijo in 1830. It was also located at the mouth of a pass at,, between Sycamore Grove and Sycamore Flat that the trail passed over and then followed westward to the Mission San Gabriel. Sycamore Grove also lay within the boundaries of the 1843 Rancho Muscupiabe land grant. From 1848, Sycamore Grove served as a stop on the Mormon Road, a wagon road between Salt Lake City and Los Angeles. In 1850, David W. Cheesman, a lawyer heading west to California with his family from Indiana on the Mormon Road, described what became Sycamore Grove: For several months in 1851 the grove was the camp for the Mormon colonists who were negotiating the purchase of the Rancho San Bernardino, that became the site of their colony, later the city, of San Bernardino.
History
In 1847, the wagon road known as the Mormon Road, between Salt Lake City and Los Angeles, was pioneered by a party of Mormons under Captain Jefferson Hunt. This wagon road closely followed the western part of the Old Spanish Trail from Parowan, diverting where necessary to allow wagons to pass. Sycamore Grove was the stop on that road at the foot of the Cajon Pass. This wagon road was used during the California Gold Rush by Forty-niners and later immigrants to California seeking to avoid the fate of the Donner Party, crossing the snow-bound Sierra Nevada in winter. Between June and September 1851, Sycamore Grove was the first camp of the parties of Mormon colonists, who founded the city of San Bernardino. They included groups led by Captain Jefferson Hunt, Amasa Lyman, Charles C. Rich, David Seely, and Andrew Lytle.
