A trip along Highway 58 is always made better with a stop at Harper Dry Lake Marsh to cleanse the mind and strengthen the soul, if you don’t mind the low hum of the nearby solar farm and the occasional distant booms of artillery from Fort Irwin.

Harper Lake contained water and a natural marsh into the early 20th century when agricultural development began to deplete the groundwater that sustained its level. The lake became dry and the marsh died in the late 1990s after the alfalfa farm next to the lake ceased operations.

Harper Dry Lake is the Mojave Desert’s largest dry lake and contains 28 miles of shoreline. Harper Dry Lake Marsh lies at its edge.  It is accessible from Harper Lake Road, which runs north off of State Route 58 midway between Kramer Junction and Barstow, and is Northeast of Edwards AFB. 

By the way, for us, the sound of far-off artillery from Fort Irwin doesn’t detract, it’s the sound of freedom.

How amazing is it that peaceful Harper Dry Lake north of Highway 58 near the small community of Lockhart is practically a stone’s throw away from the world’s second largest solar farm facilities. Inscription Canyon in the Black Mountains can be seen across from the dry lake and adjacent marsh.

This is the BLM wildlife marsh about 20 miles North-northwest of Barstow, California, and the temporary fly by for migratory waterfowl who don’t get zapped by the nearby solar farm. It has been a BLM Area of Critical Environmental Concern since 2001. In the distance is Black Mountain, the site of our recent adventures discovering petroglyphs in Inscription Canyon.

In the latter part of the 19th century, settlement in Harper Valley began in earnest. In 1869, J.W. Robinson and his partner made a temporary camp in an area of green pastures and mesquite located on the eastern shoreline of Harper Dry Lake.

Three years later, C.S. Black built an adobe cabin near here, established a cattle ranch, and began operating a stagecoach stop. Black’s Ranch, also called Grant’s Station, became a prominent landmark.

Harper Lake has its own fault zone, with estimates for seismic rupture once every 3,500 years. The last earthquake occurred sometime during the Holocene geologic era, which covers the last 10,000 years to present.

Harper Dry Lake bed in the Mojave Desert was the site of secret flight test programs conducted by the Hughes & Northrop aircraft companies during the 1940s, including the first flight by an American rocket-propelled aircraft.

Ron Most recalled, “I grew up in the Harper Dry Lake area on a alfalfa ranch & the runways are our dirt strips we used for our airplanes.

The Howard Hughes Hangar was on the lake bed.” 

SEGS VIII–IX (160 MW) is located at Harper Lake. You will see this ginormous facility on your way to the marsh. You can’t miss it.

Solar Energy Generating Systems (SEGS) in California, with the combined capacity from three separate locations at 354 megawatts (MW, 474,700 hp), is now the world’s second largest solar thermal generating facility, after the commissioning of the even larger Ivanpah facility in 2014. 

Construction of the tenth plant in the same locality was halted because of the bankruptcy of Luz Industries. Construction of the approved eleventh and twelfth plants never started.

Harper Dry Lake was also popular with land speed racers in the 1940s. Many hot rod car clubs were involved, one being the Rumblers in Southern California.
