Four hundred people once lived here. They had a post office, three general stores, a hotel, a Methodist church, and a Templar lodge. They mined copper from the hillsides and ran cattle across the grasslands. Today, Spenceville is a ghost town swallowed by oak woodland and chaparral, its mine shafts sealed, its streets gone to deer trails. The 11,448-acre Spenceville Wildlife Area, managed by the California Department of Fish and Wildlife in the Sierra Nevada foothills between Nevada and Yuba Counties, is one of those rare places where human ambition arrived, peaked, collapsed, and nature simply resumed.
Long before copper drew settlers to these foothills, the Maidu and Nisenan people shaped their lives around this landscape. Evidence of their presence remains embedded in the bedrock: grinding holes worn smooth by generations of women processing acorns, and the depressions of lodge pits where families sheltered through the seasons. The geology beneath their feet was ancient even by geological standards. The Smartville Block, a formation dating to the Middle Jurassic some 200 million years ago, underlies the entire area and forms part of California's Mother Lode belt. The Maidu and Nisenan did not mine the gold and copper locked in that rock. They had other uses for this land, and the grinding stones they left behind have outlasted every structure the settlers would build.
The town of Spenceville was born in the early 1860s when copper ore was discovered on Purtyman's Ranch. The Well Lead Mine transformed a scattered ranching community into a proper town almost overnight. Copper mining expanded with the Last Chance Mine, and by the mid-1870s Spenceville had all the trappings of a thriving settlement: stores to supply the miners, a school for their children, a hotel for visitors passing through the foothills. About four hundred residents called it home. But copper prices fell, veins thinned, and the economics that built Spenceville slowly unwound. Mining declined sharply after World War I, and the town was abandoned. During World War II, the U.S. military acquired the land for training purposes, and after the war the area was divided. Part became Beale Air Force Base. The rest became the wildlife area. A major cleanup of leftover mine waste was not completed until 2013, more than a century after the miners left.
The most popular trail in the wildlife area leads to Fairy Falls, a double waterfall on Dry Creek that locals also call Beale Falls or Shingle Falls, depending on who you ask and when they arrived. The falls tumble over exposed rock into a pool surrounded by oak and foothill pine, and in spring, when snowmelt from the higher Sierra feeds the creek, the cascade is strong enough to hear before you see it. The trail system extends across the preserve's rolling terrain, which ranges from about 200 feet in elevation at its lowest to considerably higher in the eastern reaches. Hikers, mountain bikers, equestrians, and birders share these paths. Hunters come for deer and turkey seasons, and dog field trial enthusiasts use the open grasslands for training. One practical note appears in every guide to Spenceville: rattlesnakes are common here, especially in the warmer months, and visitors are advised to watch the trail ahead rather than the scenery.
In June 2025, the Nevada County Board of Supervisors designated the Kneebone Ranch and Cemetery, located within the wildlife area, as County Historical Landmark NEV 25-06. The Kneebone family ran a 20-mule freight-wagon business through these foothills, hauling supplies to remote mining camps and settlements across the northern Sierra. Their cemetery, tucked among the oaks, is one of the few tangible reminders that families built entire lives in this landscape, not just mines. The designation recognized both the commercial importance of the freight operation and the simple human fact of the burial site: people were born here, worked here, and were buried here, in ground that now belongs to the wildlife.
Spenceville's return to wildness is not guaranteed. The Yuba County Water Agency has proposed the Waldo Dam Project, which could alter water flows that sustain the preserve's creeks and seasonal wetlands. Housing development proposals between Beale Air Force Base and the wildlife area would push suburban edges closer to habitat that currently blends uninterrupted into the foothills. Conservation groups, including the Friends of Spenceville, monitor these threats and advocate for the area's protection. For now, the oak woodlands, the waterfall, the grinding stones, and the sealed mine shafts coexist in a quiet equilibrium. The town of Spenceville is gone, but the land it occupied is very much alive, hosting deer, raptors, and wildflowers across terrain that has been traded between human ambition and natural resilience for more than a century.
Spenceville Wildlife Area is located at 39.1444N, 121.317W in the Sierra Nevada foothills between Nevada and Yuba Counties. The preserve spans 11,448 acres of oak woodland and grassland approximately 18 miles east of Marysville. Beale Air Force Base (KBAB) sits immediately to the west and is the nearest significant airfield. Pilots should be aware of restricted airspace associated with the base. The terrain is rolling foothill country with elevations starting around 200 feet. From moderate altitude, the preserve appears as an expanse of oak savanna contrasting with agricultural land to the west and denser forest to the east. Sacramento Executive Airport (KSAC) is approximately 40 nautical miles to the south.
