Stark, rock-strewn mountains rise all across California’s deserts thanks to the Pacific and North American tectonic plates colliding. A good place to explore those peaks is on the Lost Horse Mine Trail.
A 2-mile (4-miles round trip) segment of the trail heads to the base of one desert summit – Lost Horse Mountain, which rises nearly a mile above sea level to 5,278 feet.
To reach the trailhead, from Interstate 10 in the Coachella Valley take Calif. Hwy. 62 north through Morongo Valley. In Joshua Tree, turn right/south onto Park Boulevard (aka Quail Springs Road) into the national park. Just before Cap Rock, go right/south onto Keys View Road. Next, turn left/southeast onto Lost Mine Road, which quickly becomes gravel. A parking lot is at the road’s end, and the trail heads out from the lot’s southeast corner.
Little San Bernardino Mountains
The route immediately enters a low-lying arm of the Little San Bernardino Mountains. A stout range, the Little San Bernardinos run about 40 miles along the Coachella Valley’s northeast side. The mountains mark the transition zone between the valley’s Colorado Desert environment and the Mojave Desert that sits above the coastal basin.
About 2 million years ago, the Little San Bernardinos began to rise, thanks to action along the San Andreas Fault where the North American and Pacific tectonic plates slip against one another. Just about every time there’s an earthquake in the Coachella Valley, the Little San Bernadinos grow a bit taller.
The rocks making up the mountains are mainly granitic and metamorphic and are hundreds of millions of years old. Granitic rock forms when magma solidifies underground; the coarse rock usually contains a large amount of quartz. Metamorphic rock also forms underground but when heat and pressure alters the chemical composition of other rocks, such as sandstone or shale.
Joshua trees and yucca line much of the boulder-strewn trailsides. You’ll gain about 500 feet of elevation on a gradual uphill grade.
Lost Horse Mine
About 1.8 miles in, a spur off the trail heads to Lost Horse Mine. The rusted remnants of its stamp mill mark the mine’s entry. A chain-linked fence prevents hikers from walking amid the mill and entering the mine, however.
For two decades beginning in 1884, miners pulled gold and silver from the mountainside. About 16,000 ounces of silver and 10,000 ounces of gold were extracted. That may not seem like much, but in today’s dollars it’s nearly $5 million of gold.
The trail and mine got its name because one of the mine’s original owners had lost his horse while camping in the area. That’s when he met a man who told him about finding the gold and sold him his claim to it for $1000.
The Lost Horse Mine Trail actually is a loop through the mountains and from the spur heads south. Rather than take that long circle route, which adds 2.9 miles to your hike, instead retrace your steps to the parking lot.
The entire route is exposed to the sun, so be sure to don sunscreen, sunglasses and a hat as well as bring plenty of water.
