Searching For Melchior Díaz

Baja California is a land filled with history and mystery. The location of where Spanish explorer Melchior
Díaz is buried is one of the earliest North American mysteries with a Baja connection.
Following the discovery of California by Fortún Jiménez in 1533, the Spanish explored the length of the
Gulf of California with the voyages of Francisco de Ulloa in 1539 and Hernado de Alarcón, the next year.
Both expeditions proved California was a peninsula, despite that fact, many were unconvinced for the
next 200 years and continued to view California as an island.
In May of 1540, Hernando de Alarcón left Acapulco, to support the great expedition led by Francisco
Vázquez de Coronado. Coronado was seeking the ‘Seven Cities of Cíbola’ to the north of Mexico. Alarcón
was bringing supplies for Coronado when he discovered the Colorado River, but he never connected with
the Coronado expedition.
Alarcón may not have set foot on the California side of the river, but he and his men traveled up the river
many miles in small boats. After waiting a pre-arranged time for Coronado, Alarcón returned to his ships
at the head of the gulf, but left letters at a large tree and knew the natives would direct any Spaniards to
Marching west from the Coronado expedition to meet Alarcón was Melchior Díaz, with many Indian
guides, and his troops. Díaz missed Alarcón by just days but found the message left in a jar at the base of
the tree. The news from Alarcón released Díaz from his duty to retrieve supplies for Coronado. That
allowed Melchior Díaz to explore the new land, west of the river. Díaz named the river ‘Firebrand’ noticing
how the Indians kept warm with glowing sticks that December of 1540. The sticks were like fire heated
branding irons. Díaz crossed the river using rafts, and he would be the first European land traveler to enter
California. Díaz was injured in a freak accident and he died several days later, January 8, 1541. Where he
was buried remains a mystery.

The story about Melchior Díaz was told by Pedro de Castañeda de Nájera in his book ‘Narrative of the
Coronado Expedition’: After entering California, the Díaz expedition encountered the boiling mud pots on
the west side of the Colorado Delta, later called Volcano Lake. This is at the base of Cerro Prieto volcano,
20 miles south of today’s city of Mexicali. On the fourth day on the California side of the river, Captain Díaz
suffered the mortal injury. A greyhound belonging to one of the Spaniards was annoying the flock of sheep
they had along for food. Captain Díaz chased the dog on horseback and threw his lance at the animal. The
lance missed the dog and stuck in the sand. Unable to turn his horse soon enough to avoid running over it,
the lance pierced Melchior’s thigh and bladder.
Castañeda says the men returned across the river and that Melchior Díaz lived for twenty days on the
return trip. While most believed his men returned across the Colorado River with Díaz, there are some
who think the men followed the coastline south, trying to reach Alarcón’s ships. It is this possibility that
sparked a light in the mind of desert explorer Walter Henderson when he read the story of Melchior Díaz.
During the depression of the 1930’s, Henderson and a companion traveled south of Mexicali seeking the
exotic blue palm trees of the canyons of Baja California. He heard from a prospector that some were in
the Sierra de Las Tinajas and Sierra de La Palmita. These two small desert mountain ranges are about 70
miles south of the Mexicali border and 20 miles west of the road to San Felipe.
The clues of where Walter Henderson hiked and found the pile of rocks were given by Henderson using
the 1962 Lower California Guidebook Map 3.
Henderson writes that they left the San Felipe road about 20 miles south of La Ventana and traveled west
to the base of the Sierra Pinta, as far as his Model A Ford would take them. The next morning they traveled
into the hills, using the most obvious of routes to reach the Sierra de Las Tinajas. They would discover that
they began their hike too far south to reach that mountain, within the limits of their time and water
supply. They reached the top of the Sierra Pinta range and then went steeply down the west side, into
Arroyo Grande. Around noon, roughly 1/4 to 1/3 of the distance down from the divide, Henderson says
they came upon a large and very unnatural looking pile of rocks. It was on the north side ledge of the
rocky ravine. No sign of any human presence, such as wood cutters or prospectors was near here, so it
seemed most odd. The rocks were coated with desert varnish, indicating they were placed many, many
years or even centuries ago.
The article by Choral Pepper featured in the August 1981 edition of Desert Magazine.
They made camp that night in Arroyo Grande, and returned the next day to the Model A by traveling up
Arroyo Grande to the base of Borrego Mountain and then back east to the car. Years later, Walter read
about Melchior Díaz and the lost grave. This Spanish captain was a highly respected man and would have
been buried with his possessions. Walter Henderson believed his rock pile could be the missing grave and
made several attempts to have the Mexican government follow his route and protect or extract the
remains for their great historic value. The answer he got was that he would have to finance the expedition
if he wanted Mexico to save the treasure and put it in a museum! Not a remote chance of that happening
and so Melchior Díaz, or perhaps just a ‘pile of rocks’ remains to be rediscovered.

Many years later, writer Choral Pepper shared Henderson's story in her 1973
Baja California book after he sent her a letter about the finding. Henderson provided details and
directions to a ‘rock pile’ he found in Baja. Since Mrs. Pepper was the editor of Desert
Magazine he thought she could be a great outlet for sharing the
discovery with fellow desert enthusiasts who might have an opportunity to find the possible 1541 grave
site. The story was featured in the August, 1981 edition of Desert
Magazine, but this time with more location details. It was from this magazine story that excited San Felipe desert
explorer Bruce Barber who spent a great amount of energy analyzing Pepper’s story using science, and
searched the desert hills north of San Felipe. The problem is that Pepper’s 1981 story gave an incorrect
starting point for Henderson’s hike. I know because I have the original 1967 letter Walter wrote to Choral.
I have since shared the letter with Bruce Barber, who had so much passion for finding the Díaz grave and
devoted much of his 2003 book “...of Sea and Sand” to the search.
Choral Pepper passed away in 2002 and wanted me to continue my sharing of the Baja history that
is so exciting to many, so she instructed her family to leave her Desert magazine Baja related photos and
letters to me. In 2009, I found her ‘Lost Mission’ of Santa María Magdalena. In
2015, I hoped to find the other mystery that remained: the rock pile location.

The following are critical notes from Walter's letter to Choral Pepper:
- Henderson traveled south of La Ventana approx. 20 miles before turning west.
- Henderson mentions the road shown by El Chinero.
- Henderson went about 5 miles south of that road, then turned west.
- Henderson drove to the base of the hills and parked (Red Arrow).
- On Day 1 of the hike, Henderson found the rock pile at noon about 1/4 to 1/3 down towards Arroyo
Grande from the divide, and then camped in Arroyo Grande that night.
- On Day 2 Henderson walked back to the Model A from the base of Cerro Borrego.
In April of 2015, four friends (Tom, Joe, Karl, Harald) and I camped in Arroyo Grande and explored 3 possible
canyons coming down the Sierra Pinta. It was about 10 miles from
the Model A parking spot to the divide. Arroyo B (blue line) is 3 miles long.
The middle canyon (black line) I named ‘Arroyo A’ and a small dam at its entrance required a detour
climb around to enter the lower region. Beyond there were just a choice of narrow gullies blocked by
boulders. Two of our group climbed up to the top of the canyon ridge but found no clear arroyo path
higher. The south canyon (yellow line) was named ‘Arroyo D’ in my pre-trip planning. We could actually drive up
it for some distance before beginning the hike. That promising feature soon ended as the canyon
narrowed and got steep. A surprise was finding a large cave and made the hike that much more
interesting. The north canyon (black line) is my ‘Arroyo B’, and was my first choice to explore. However, a week prior
to our trip, another friend (Paul) discovered an impassable dry waterfall making it unlikely for
Henderson or the Díaz Party to have used it. Paul hiked into Arroyo B from Arroyo C, which ends in
Arroyo Grande, further north.
Sadly for us, all three routes up from Arroyo Grande had rock obstructions that made getting to the
divide seemingly impossible. No way could horses and a man on a stretcher pass, unless the canyons
were far different than today. A helicopter would seem to be the best way to find the rock pile!
The 1930’s rock pile found by Walter Henderson and the 1541 grave of Melchior Díaz remain to be
found somewhere in the desert of Mexico. Should you have the good fortune to find them, this author
(and many other history buffs) would be very happy to hear from you!
The giant log just inside Arroyo B was quite a surprise and mystery of where it came from in these desert
hills. It made a perfect place for me to sit and wonder..
Detouring high up and around the dam at the start of Arroyo A with me is Tom and Joe. I know they
think I am nuts!.
