About this map

Hot Mineral Spa and a nearby Tropical Fish Farm anchor a small pocket of activity within this desert landscape along the border of Riverside and Imperial Counties. The map illustrates the sophisticated water infrastructure required for life in the region, centered on the Coachella Canal as it winds past a series of numbered siphons, including Siphon 17 and Siphon 23. This engineered corridor stands in contrast to the natural arid terrain of the Chocolate Mountains, which here serves as an Aerial Gunnery Range.

Transportation and industry define the western flats, where the Southern Pacific tracks run parallel to a Mining Railroad and a network of levees. The presence of several Rock Quarry sites and a Gravel Pit suggests the extraction of mountain materials to support the expansion of rail and canal projects. Seasonal water patterns are evident through the course of Salt Creek and various unnamed springs, marking the transition from the high desert peaks to the lower canal zones.
