Part 4 — The Three Rocks Problem
Designing a Mission to Test the 1839 Taos Gold Legend
At first glance, the description of the burial site in the True West article sounds almost too simple.
The ambush and burial are said to have taken place near three large rocks that provided defensive cover for Cortez and the surviving packers.¹
That phrase appears several times in the account.
But once you begin trying to map it onto a real landscape, a surprising problem appears.
The American Southwest is filled with rocks.
But three rocks that meet the conditions described in the story are actually far less common than they might seem.
What Counts as “Three Rocks”?
The article does not describe a cliff or a large ridge.
Instead, it repeatedly references three individual rocks that the defenders used as a fortification.
For the account to make sense tactically, the formation would need to satisfy several conditions:
• The rocks must be separate objects, not one continuous formation
• They must be large enough to provide cover from rifle fire
• They must be close enough together for defenders to move between them
• They must be located in terrain where attackers could approach on horseback.
These constraints rule out many types of formations common in the region.
For example:
Large cliffs or canyon walls would not match the description.
Neither would small scattered stones or low boulder fields.
Instead, the story implies a cluster of three prominent boulders or rock towers rising from otherwise open terrain.
Why the Rocks Matter
This detail is more important than it might appear.
Frontier travelers often used distinctive rock formations as navigation markers.
In landscapes where many hills and valleys look similar, unusual rock features become natural landmarks.
If Cortez described the burial site years later, it would make sense that he remembered it in relation to a formation that stood out visually.
Three large rocks close together would be exactly the kind of landmark a traveler might remember.
Especially after a violent event like an ambush.
Defensive Positioning
The story also suggests the rocks formed a natural defensive position.
According to Bailey’s account, Cortez and De Grazzi tied the mules to the rocks and used the formation as cover while exchanging fire with the attackers.¹
That detail implies the rocks formed something like a triangle or partial enclosure.
If the rocks were positioned roughly in a triangular pattern, they would allow defenders to:
• shield themselves from incoming fire
• move between positions
• maintain sightlines across open terrain.
That type of natural fortification appears occasionally in volcanic landscapes where large boulders break off from outcrops and settle nearby.
Northern New Mexico contains many such formations, particularly in areas shaped by volcanic activity and erosion.
But even there, exactly three large rocks positioned close together is relatively rare.
Geological Possibilities
Several geological processes could produce the type of formation described.
One possibility is a tor formation, where erosion leaves isolated blocks of resistant rock standing above the surrounding ground.
Another possibility is a cluster of large volcanic boulders that have fallen from a nearby ridge.
In the high desert east of Taos, many prominent rocks consist of volcanic basalt or weathered sandstone.
Both can produce isolated pillars or boulder groups that stand out dramatically from the surrounding terrain.
These kinds of formations would be easy to recognize from a distance - and easy to remember.
Two Centuries of Change
Another complication is time.
The ambush described in the article occurred around 1839.¹
That means nearly two centuries have passed since the supposed burial.
Over that span of time, landscapes can change significantly.
Possible changes include:
• erosion that partially buries smaller rocks
• collapse or splitting of larger formations
• sediment accumulation around the base of rock features
• vegetation growth altering visibility.
However, truly large rock formations tend to remain relatively stable over long periods.
If the rocks described in the story were substantial enough to provide rifle cover, they likely still exist today — although their surroundings may look different.
Searching for Three
If the burial site really was associated with three prominent rocks, the search strategy becomes very different.
Instead of scanning the landscape randomly, an investigation could focus on identifying candidate formations that meet several criteria:
• three distinct rocks
• sufficient size for cover
• location near historic travel corridors
• within roughly forty miles east of Taos.
Modern tools such as satellite imagery, digital elevation models, and geological surveys make it possible to scan large areas for formations that match these conditions.
In effect, the phrase “three rocks” becomes a filtering tool that reduces the search space dramatically.
The Burial
The rocks themselves were not the hiding place.
According to the story, the gold was buried near the formation, not inside it.
After the ambush, Cortez and the surviving packers reportedly dug a trench to conceal the coin-filled containers.
They then masked the disturbed soil with ashes and debris to hide evidence of digging.¹
That detail suggests the gold would likely lie:
• somewhere within a short distance of the rocks
• in soil that could be excavated by hand tools
• in terrain not dominated by solid bedrock.
In other words, the burial site would probably be adjacent to the formation, rather than directly beneath the rocks themselves.
The Real Question
So the problem now becomes much more specific.
Not:
Where is treasure hidden in New Mexico?
But:
Where are there three large rocks near a historic travel corridor about forty miles east of Taos?
That is a question that can actually be investigated.
And once we start investigating it, a much bigger question appears.
Did the gold described in the story ever exist in the first place?
That’s the issue we’ll tackle next.
