Loaded boys. Muchachos cargados.
According to legend two Hispanic boys, imitating their prospecting fathers, returned to their family's camp in the Sierra de San Pablo Mountains one night with their shirts full of gold. This was in the 1890s. Their discovery renamed a mountain range.
The Sierra de San Pablo Mountains became the Cargo Muchacho Mountains. They jut abruptly from the desert floor of eastern Imperial County and have been there for millions of years. They are immersed in mining history including the Tumco Mining District, American Girl Mine and Jackson Gulch at the southern end of the range.
Jackson Gulch? About 100 years prior to the "loaded boys" discovery, gold was found in Jackson Gulch. During the 1770s Spanish explorer Father Francisco Garcia recorded rich-appearing deposits in the Jackson Gulch area. These deposits were first worked by Hispanic miners and their work may still exist, as vertical and horizontal mine shafts or prospects that pock mark the canyon walls and sediments of Jackson Gulch.
