An off-duty firefighter searching for a stray dog fell into a hidden mineshaft in Nevada County and was brought to safety by rescuers, according to the Sacramento Bee and ABC7 San Francisco. The reports differ on the depth of the fall: the Bee said 30 feet, while ABC7 described about 40 feet. The discrepancy does not change the immediate danger, but it is a reminder that details can vary across accounts.
The rescue is one documented emergency amid a much broader, imperfectly mapped legacy. ABC7 reports that California has recorded at least 47,000 abandoned mine sites and that state figures count at least 185 deaths since 1950, along with 443 incidents involving injuries or near misses. The state’s 2007 priority-list letter cautioned that the lists were only a snapshot and that many sites had not yet been inventoried or assessed; that historical warning describes a limitation in the records at the time, not the completeness of today’s count, according to the California Department of Conservation.
Different sites, different hazards
A separate California case shows how a mine hazard can affect a home rather than a trail: ABC7 reported that Jason Chellew died after falling into an abandoned mine beneath his family’s Napa-area property in 2006, and that his dog also fell in while trying to reach him. The incident is distinct from the Nevada County rescue, but both involved a shaft whose danger was not apparent to the person nearby.
Abandoned mine hazards are not limited to open shafts. In a 2019 account, the California Department of Conservation said an abandoned shaft opened beneath LaBarr Meadows Road near Grass Valley. That was a roadway subsidence event, not a report of someone falling into a mine, and illustrates a different way an old mine can pose a public hazard.
The California State Lands Commission says most abandoned mines are on federal public lands, while others are on private or state lands overseen by different agencies. It also says possible remedies range from signs to permanent closure, selected case by case according to the severity of the public hazard. That division of responsibility and range of remedies mean the site count alone does not say which agency will address a particular mine or what action it will take.
Safety and reporting
The California Department of Conservation’s guidance says to call 911 or the local sheriff if someone falls into or is trapped in a mine, and not to attempt a rescue without proper training and equipment. To report an abandoned mine, the department asks people to email [email protected] or call 877-OLD-MINE (877-653-6463), providing the location and a description, according to its Abandoned Mine Lands guidance.
