Alamo Solo Spring, also called Lone Cottonwood Spring, lies in California’s Pyramid Hills east of Dagany Gap. Long before the Spanish period, it was the site of a large Indian village covering about one hundred acres. It later became one of the most reliable watering places on El Camino Viejo in the San Joaquin Valley, between Arroyo de las Garzas and Aguaje de la Brea. Here the old road divided: the main route continued north, while an eastern branch ran past Alamo Mocho, along Tulare Lake, across the Kings River, and through settlements on the Fresno Slough and San Joaquin River before rejoining the main road at Arroyo de Panoche Grande.
