History
The Luiseño were the original inhabitants of what later would be called the San Jacinto Valley, having many villages with residents. The Anza Trail, one of the first European overland routes to California, named after Juan Bautista de Anza,4 crossed the valley in the 1770s. Mission padres named the valley, San Jacinto, which is Spanish for Saint Hyacinth, and around 1820 they established an outpost there. On July 15, 1937, San Jacinto was the end point for the longest uninterrupted airplane flight to that date when Mikhail Gromov's crew of three made the historic polar flight from Moscow, USSR, in a Tupolev ANT-25. This flight followed another similar historic flight over the pole when Valery Chkalov's crew of three ended up in Vancouver's Pearson Airfield earlier that same year. With these two flights, the USSR earned two major milestones in the Fédération Aéronautique Internationale (FAI) flight records. In the early 1950s the fraternal group E Clampus Vitus and the Riverside County Department of Transportation commemorated the Gromov flight by erecting a stone marker on Cottonwood Avenue, just west of Sanderson Avenue in west-central San Jacinto. The landing site is also marked by California State Historical Landmark Number 989.
