Rock Spring Mojave National Park Rock Spring Loop Trail Rock House Hike

Water is something you don’t see much of in Mojave National Preserve, certainly not just pooling on the ground as it does at Rock Spring. The constant source at Rock Spring helped inhabitants survive in the Mojave Desert for thousands of years and was even the site of a small U.S. Army post in the 1860s. Today you can reach the spring easily, along with a Rock House built in the 1920s and the ruins of a mill used by miners, on a 1 1/3-mile loop with 100 feet of elevation change that also features panoramic desert views.

At first glance, the desert can seem like a big empty place, but there is a lot to see on this short loop. Start from a parking area off Cedar Canyon Road in a remote but relatively central area of Mojave National Preserve. Pass through a gate and walk up a driveway toward the Rock House. A sign reading “come on up!” lets you know that you’re welcome. There is also a table beneath a juniper tree on the left side of the trail, where you can sit for a picnic.

After a tenth of a mile, you will reach the Rock House, a cabin with walls made of rocks collected nearby. Beyond the house to the south, you will see similar colored boulders on the hill that rises above Rock Spring, farther to the southwest, you’ll also spot the flat summit of Table Top Mountain. The Rock House was built in 1929 by a man recovering from an exposure to poison gas during the First World War, as a panel outside the house explains:

While fighting in Europe during World War I, Bert Smith was exposed to poison gasses used during that war. Returning to the U.S. with scarred lungs, Bert eventually moved to the Mojave Desert in the late 1920s. When Bert built his Rock House and started living here in 1929, it was a desperate attempt to regain his health. Although he expected to survive only a short time, he lived here until 1954 – 25 years!

Maybe there was something in the water?

The loop trail to Rock Spring begins on the right side of the Rock House. The dirt track heads south across the desert for 0.15 miles to the ruins of a miners’ mill. The mill was used briefly in the 1930s when prospectors crushed rocks from nearby Watson Wash to release copper ore. Like so many desert mines, the prospect proved unproductive and was abandoned.

Continue down the trail and you will pass through a cattle fence after another 0.05 miles. The trail drops into a ravine bordered by dark boulders. At the bottom of the ravine, 0.5 miles from the start, you will reach a junction at the edge of Watson Wash. The loop trail continues to the left, but first turn right to reach Rock Spring.

In a few hundred feet you will spot the spring, set beneath stone cliffs in a small canyon off Watson Wash. You should see water pooling around the rocks, although at times the spring can appear dry. Venture up the rocky canyon to find a string of stagnant pools. None of the water looks too appealing to drink today (unless there is a stream from recent rain), but in the past Rock Spring was a rare source of desert salvation, as a panel explains:

For thousands of years, Rock Spring was a crucial link in a chain of springs that allowed early travelers to cross the unforgiving desert. American Indians, then miners, then cowboys – all stopped here to quench their thirst and rest before moving on.

When you are ready to move on yourself, walk back out from Rock Spring to the loop trail and continue east toward Watson Wash. In just a couple hundred feet you will pass a panel at the site of Camp Rock Spring, a briefly established U.S. Army post. The panel explains:

This is the site of Camp Rock Spring, a U.S. Army post established in the late 1860s after gold and silver were discovered in the Arizona Territory and Prescott became its capital. The citizens of Prescott needed dependable mail service because all supplies and manufactured good for the area came from California. The Army set up a string of posts to protect this mail-and-supply route on the Mojave Road.

Camp Rock Spring closed after just 17 months, when the mail-and-supply route was shifted to a new road farther to the south.

A few hundred feet farther down the trail, you will find a plaque built into a rock honoring the men who served at Cap Rock Spring. Just past the plaque, Rock Spring Loop Trail turns left and climbs above Watson Wash. The trail ascends a round ridge and delivers broad views up and down the desert wash. The Hackberry Mountains rise above the wash to the southeast. In the other direction, to the northwest, there are views of nearby Pinto Mountain. The most impressive mountains are farther north up Watson Wash, the New York Mountains, which are one of the larger micro-ranges in Mojave National Preserve. If you’re intrigued by the New York Mountains, you can check out an on and off-trail hike to the summit of New York Peak.

After hiking 0.55 miles past Camp Rock Spring, the trail will return to the Rock House. Turn right and walk a short distance back down the road to the parking area where there is a vault toilet. No fee or permit is required to hike Rock Springs Loop Trail in Mojave National Preserve, so get out and enjoy!

    I lived in the Rock House in the Mojave National Preserve. This would have been in about 1982-84. I replaced the caved-in roof and built new window and door casements and replaced the windows and doors. Also installed the kitchen cabinets and a propane fridge and stove. This was before it became the preserve and was surrounded by BLM land. It was owned by the Eldridges, a local ranching family at that time. I have since written about that experience in a book called The Ogallala Road.
