Inside the Year-Long Paranormal Investigation at Hotel del Coronado

Most ghost investigations last a night.

This one lasted a year.

In 1992, Hotel del Coronado hired parapsychologist and anomalist Christopher Chacon to investigate reports of strange activity throughout the historic resort.

According to the hotel's own historical account, the project ran continuously for 12 months and produced almost 10,000 hours of onsite assessment.

It involved environmental monitoring, remote scanning and interviews with approximately 1,100 people.

And investigators said they documented incidents they could not scientifically explain.

But did they prove the Hotel del Coronado is haunted?

That's a very different question.

Why Investigate The Del?

By 1992, Hotel del Coronado already had a century of history behind it.

Its best-known ghost story centered on Kate Morgan, the young woman who checked into the hotel under an assumed name in November 1892 and was found dead five days later.

Over the decades, guests and employees reported flickering lights, unexplained footsteps and voices, cold spots, moving objects and apparitions.

The stories had become part of the hotel's folklore.

Instead of merely repeating them, The Del commissioned a lengthy investigation.

This Wasn't an Overnight Ghost Hunt

The scale is what makes the 1992 project unusual.

The hotel's account describes a 24-hour-a-day, 12-month investigation using equipment placed throughout rooms, grounds and other areas of the resort, along with remote monitoring from a mobile laboratory.

Investigators attempted to record environmental conditions around reported incidents rather than relying only on witness stories.

What Were They Measuring?

According to Hotel del Coronado, investigators monitored an extensive list of environmental variables, including:

Temperature
Electrostatic emissions
Air currents and air content
Electromagnetic and geomagnetic conditions
Radiation
Vibration and movement
Air pressure and humidity
Light spectrum

The basic idea was sensible: if someone reported an unexplained cold spot, moving object or unusual sensation, investigators wanted environmental data that might reveal a conventional cause—or at least document what was happening at the time.

Then They Interviewed 1,100 People

The investigation wasn't limited to instruments.

The hotel says approximately 1,100 guests, visitors, employees, workers and contractors were interviewed confidentially.

About half had reported unexplained experiences. The other half were randomly selected and used as a comparison group.

That approach is noteworthy because it attempted to compare people who reported experiences with people who did not.

Almost 10,000 Hours Later...

Hotel del Coronado says the investigation documented recurring phenomena that could not be scientifically explained during the assessment.

The reported incidents included chairs and furniture moving, shadow-like forms, doors and windows opening or closing, faucets turning on and off, concentrations of unusually cold air, and unexplained voices and footsteps.

Investigators also recorded reports from people who said they heard, smelled or interacted with something that monitoring equipment did not detect.

The Fifth Floor Became Especially Interesting

Kate Morgan's third-floor room receives most of the attention, but the investigation also focused on a fifth-floor guestroom in an area that historically housed hotel staff.

Historic Hotels of America says the investigation documented more than 400 anomalous incidents in Room 3519.

The hotel continues to identify both its third- and fifth-floor rooms among locations associated with reported activity.

So...Did They Find Ghosts?

This is where good history and good skepticism need to meet.

The hotel describes the documented incidents as anomalous or paranormal phenomena that investigators could not scientifically explain.

But “we could not explain this” is not scientifically equivalent to “a ghost caused this.”

There are many possible reasons an event may remain unexplained: incomplete data, environmental variables that weren't measured, equipment limitations, human perception, coincidence or ordinary causes that simply weren't identified.

There's Another Important Limitation

The investigation is described primarily through the hotel's own historical materials and later accounts.

That makes it fascinating historical documentation, but it is not the same thing as independently replicated, peer-reviewed scientific evidence establishing paranormal activity.

That's an important distinction because the story becomes more interesting—not less—when we separate what was reportedly observed from what those observations actually prove.

Even Contemporary Reporting Was Cautious

A 1993 Los Angeles Times story reported on Chacon's work and described equipment used to monitor magnetic fields, humidity, temperature fluctuations and electronic emissions.

The same article also included skeptical voices around the hotel's broader ghost legend.

That mix of fascination and skepticism has followed The Del's paranormal reputation ever since.

Why the Investigation Still Matters

Whether or not you believe in ghosts, commissioning a year-long investigation says something remarkable about the strength of the Hotel del Coronado legend.

This wasn't simply a spooky story told during Halloween.

By the early 1990s, reported experiences had become significant enough that the resort devoted an extraordinary amount of time to examining them.

Chacon later returned to conduct additional assessments using different investigative approaches.

And The Del Still Embraces the Mystery

The hotel continues to publish its history of the investigation and the Kate Morgan story.

Its haunted reputation has become part of the cultural history of the property.

That's appropriate for a Victorian hotel that opened in 1888 and has accumulated generations of stories from guests, employees and visitors.

Old buildings don't need ghosts to collect mysteries.

Sometimes a century of human experience is enough.

The Most Interesting Answer May Be “We Don't Know”

Did investigators document unusual incidents?

According to the Hotel del Coronado, yes.

Did they monitor the property for nearly 10,000 hours and interview approximately 1,100 people?

Again, according to the hotel, yes.

Does any of that scientifically prove that Kate Morgan—or another spirit—walks the halls?

No.

And that's exactly why the story has survived.

More than three decades after the investigation, there is still enough mystery left for people to argue about what happened.
