Mine Wash lies along a direct route between Mt. Laguna and the Salton Sea. The sea today is a pale cousin of the ancient freshwater Lake Cahuilla, which was periodically formed by the overflow of the Colorado River and which provided home to thousands of native people around its shorelines. The Kumeyaay Village site lies along the best route from the ancient lake to the Laguna Mountains to the southwest, the ancestral home of the Kwaaymii, the last natives to use the Mine Wash site. To hike to the mountains, continue south to the upper end of the wash, the nape of Mescal Bajada, through Mine Canyon and on into Earthquake Valley, where lookalike bouldered hillsides embrace another village site.
The blue waters of the Salton Sea can be seen through the Narrows to the northeast from the site, but as you explore the gentle hills west of the site for this nice vista, watch out for the rambunctious “Jumping Cholla,” aka Teddy Bear cactus–but in no way are they soft and fuzzy close up.

With our spring rains of 2016–making it past the Julian rain shadow to the desert–the burst of color around the Mine Wash cultural site was worth a few spines around the boot edges. Just remember when you visit, wear solid hiking-type boots, because regular walking shoes can admit the spines readily, and getting the little jumpers off–once they stick your skin–is going to be regretful. The rough edges of a heavy rock or boulder lying nearby is sometimes your best friend.
If you’re looking for an ocotillo forest, Mine Wash is one of the best areas to find these beautiful plants in sufficient density to obtain good photos, as well as actually be shaded by clusters of them. Desert color can sometimes be a sprinkle here and a dab there, but after a good drink the forests of brilliant vermillion-crowned ocotillo seem to float above the desert floor like glowing candlesticks.
The white-lined sphinx moth, also known as a hawk or hummingbird moth, can be found in Anza Borrego in the spring and after summer monsoon rains. It is a fairly common moth with a range from Central America to Canada. Most people visiting the desert see the caterpillar form, which voraciously eats some of the desert annual flowers during the daytime. It most prefers to eat the dune evening primrose and brown-eyed primrose plants, which are plentiful annuals after a rainy winter. The caterpillars grow quickly and can reach 5 inches in length. Their markings vary, but most of the ones in Anza Borrego are a mix of green and black; they range from almost all black to a mix of black and green stripes to the more rare mostly green form. The larger caterpillars can move quickly and will cross roads when looking for food. Once they are mature, the caterpillar digs a shallow hole in the sand by moving its upper body back and forth. It then pupates underground, with the sand providing protection while it waits for the right conditions to wriggle up from the ground and emerge as a moth. The adult moths mostly fly from dusk to dawn and look like a grey blur with a plump body and fast wings that hovers by a flower to feed before flying off to the next plant. From a distance they look like a tiny hummingbird. Both the moths and the caterpillars can carry pollen between flowers, helping to pollinate the plants and start the next generation.
During prolific years, there can be hundreds of thousands of caterpillars in the area northwest of Borrego Springs, such as off of DiGiorgio Canyon Road and Henderson Canyon Road. They will quickly eat the primrose plants before moving to the next area. As each female moth can lay hundreds of eggs, it doesn’t take very many moths to produce this many caterpillars. The migrating Swainson’s Hawks and reptiles will eat the caterpillars, but during prolific years this probably does not greatly reduce the caterpillar population.
