I thought I might catalog some of the prehistoric ag
items you might find while wandering around our
LITHICS - most any rock that appears to
have been purposely broken. Especially
if distinct from all the other local rocks.
REWORKED LITHICS - Similar rocks that
appear to have secondary chipping. Typically
flakes are knocked off a core. The flakes are
then reworked into tools.
POTSHERDS - Broken pieces of pottery.
Differ from rock by their uniform thickness
and grainy interior. Very rare in ag sites.
TRADEWARE - Fancier potsherds that are
decorated by paint or slip. Often dateable
and strong indicators of trade patterns .
MULCH RINGS - Circular rock groupings
typically three feet in diameter. Often found
as a dozen or so in a spaced group. Likely
used to retain moisture for a single agave.
Sometimes wrongly called a "cairn".
ROASTING PIT - Similar rock groupings
somewhat larger in diameter but always with a
distinct internal depression.
CHECK DAM - Small semicircular rock
arrangement across a drainage. Forms a
small upstream "field", often five feet square.
APRON - Secondary rock structure below
a check dam, apparently to prevent erosion
by slowing water overflow .
CANAL - Often looks like a very smooth
hiking trail. Always flat with a very slight
slope. Very long. Purpose oriented.
LINEAR FEATURE - Rather long and
rather straight low rock wall across a
gentle slope. Forms an upslope field.
TRINCHERA - Definition varies.
May be a longer and not as straight
low rock wall used for water control.
Often associated with steeper slopes.
Easily confused with CCC boondoggles!
GRID ELEMENT - A rectanglar low
rock border, typically twelve by twenty
feet across a usually gentle slope. May
rarely have a single mulch ring in the middle.
GRIDS - A grouping of grid elements.
aranged side by side or sequentially
up slope. Tens of thousands (!) of these
appear to be locally present.
FIELD HOUSE - Single rectangular
group of higher rock walls, typically six feet
square. Always at an ag site when present.
HABITATION SITE- Multiple rectangular
grouping of higher rock walls. Often associated
with potsherds and trash dumps. Almost
always destroyed by extensive pothunting.
Normally somewhat distant from ag sites.

The number and stunning variety of "off the bajada"
prehistoric ag sites here in our Gila Valley continues to
amaze me. It is enormously difficult to wander around
outside without finding a new and unexpected one.
Virtually all of our mountain fed streams seem to have
elaborate canal systems whose 13th century engineering
appears well beyond stunning. Some of these exceed
ten miles in length; others are hung on a mesa side
90 feet above the local terrain; and others include
aquaducts that are well above grade. One appers to
have a "three way switch" that routes water to a
triad of wildly different drainages. And flows to this day.
It is not unreasonable to conclude that the 13th century
population may have exceeded the present day one.
Yet an enigma remains: The number of ag sites vastly
exceeds the number of known habitation sites.
As best as is known, the entire system was a giant
booze factory, converting agave into mescal.
Or, alternately the related ag grids were the first instance of
prototypical Dilbert cubicals. The Alice PMS Revolt of 1385
would clearly explain the latter decline in population.

Turns out the OTHER new Safford water tank is also an

habitation and agricultural sites.
So far, it plowed right on through the twin boobs canal. I've yet

prehistory, compared to the other water tank which has taken out
both prehistoric as well as totally unique CCC depression projects .

lichen contrast appears too high for prehistoric. As does the

The concept of "Lets keep the Cave / Fossil / Ruin / Hike a
secret so the bad guys can't find it" never was a very
good idea. These days, web and other developments make
the concept wildly less than utterly useless.
The first hints that all was not well emerged many decades
ago when the stunning discovery was made that the secret
dirty hippy insider underground publication for everybody
ripping off the phone company was ----> The Bell System
Technical Journal! And that the key component needed
was included free in every box of Captain Crunch cereal.
Long before the Streisand Effect.
Back then, you actually had to know what a technical library
was and where to find one. And going to a remote physical
location involved several trips and a lot of luck. Rather than
simply saying N 33.16482 W 110.70876. GPS, of course.
Many thousands of people are now routinely into orienteering
and especially geochaching. Making finding any location trivial.
And freely publishing it world wide even less so.
Having the location instantly gives you a topo map and detailed
satellite imagry via Acme Mapper. Or land ownership via
GIS sites such as this one or tax roll sites such as this one.
And most everybody now has ready access to the insider'e
papers and publications. Or shortly will have. Such seemingly
innocuous inclusions as including two foot contour lines on
a ruin site sketch can tell you exactly where the ruin is in a few
minutes of topo searches. As can fitting two bends in a stream.
Doing your own low cost aerial photography has become
trivial, and shortly should approach super cheap.
As with such stupities as DRM or copy protection or draconian
NDA's, there always will be more bad guys than perceived good
ones. And they always will be smarter than you and always will
have accesss to more research materials and more time to
patiently explore nonobvious links and obscure source materials.
Yet another approach involves the Freedom of Information act.
But this route instantly brands you as a bad guy and draws
attention to yourself.
So, excessive secrecy is almost always totally pointless.
Besides usually having the exact opposite of its intended
One possible solution is not drawing attention to something
"secret". By not being that way in the first place. A second
is to actually trust people who, on the average, are likely to

on their location, but exactly tell you how "they" found it.

One of the many enigmatic mysteries of the 1898
Safford to Morenci toll road is "Why is there a
PVC pipe inside the shoulder rockpiles?
My guess is this:
The original road construction consisted of removing
rocks and piling them on the ( usually southern ) edge
of the ten foot wide pathway. These rocks were then
loose and formed a continuous bunker some three feet
or so wide and two feet or less high.
Ranchers like to bury their stock tank PVC to keep
the water cooler, minimize damage, and prevent
ultraviolet lifetime trashing. Digging a "real" trench
through extremely rocky soil is both expensive
and time consuming. Not to mention painful.
So, my guess is that they simply laid the
pipe BESIDE the shouldder rockpile and then
MOVED the loose rocks over to cover.

As a general rule, any topo map feature named
"cave" or anything remotely suggestive has long
ago been checked by Southwestern cavers.
Cavers use binary geology: There are two kinds
of rock, limestone and shit. Except for some
minor lava and gypsum examples, juat about
all decent caves demand limestone. Not just
limestone, but a karst topography where water
can create sinkholes and such.
One intriguing area I have yet to explore is the
"Pothole Country" six miles north of Mule
Creek. There's also a "Cave Canyon" and
a "Pothole Canyon" in the immediate area.
"Pothole" can have several meanings. No
telling exactly what they had in mind.
The geology is almost certainly a useless
volcanic mudstone, and the area seems little
known to cavers. While on Gila National
Forest, a long ago exploration attempt
met with distinctly unfriendly local ranchers.

Found the original documents for the McEniry Tunnel!
This was a scam ( then called a swindle ) to tunnel
clear thru Mount Graham for a total distance of
twelve miles, revealing untold riches in gold and
silver, besides $300,000 worth of timber and 45,000
horsepower worth of hydro. The leftover water
would irrigate at least 25,000 acres by using 30
miles of canals.
The total known mineralization of Mount Graham,
of course, is approximately zero. There are only
the tiniest mineral explorations of no consequence
at the extreme range ends. The rock is all intrusive
precambrian gniess or granite. Neither PD nor FM
has expressed the slightest interest in this range.
Getting info on this "somewhat optimistic" proposal
has been tricky. First because it originally was
called the Triumph Tunnel, and later referred
by locals as the Mammoth Graham tunnel.
Over the years, a number of misspellings of
"McEniry" confused the issue. The spelling
here comes from his signature on the above
document. Many credible sources ( including
Arizona Place Names ) have gotten it wrong.
The tunnel was only driven a few hundred feet
and remains of interest today. It is just a plain
old empty horizontal mineshaft. Easily visited.

Made two more trips to the cliffhanging canal. And
the engineering remains orders of magnitude beyond
What we have here is a thirteenth century canal system
literally hung on the TOP edge of a steep mesa. Often as
much as NINETY FEET above the valley floor. As part
of a system that is at least 12.5 kilometers (or eight
miles) long. Not to mention several hundred feet of
above grade aquaduct!
Major portions of the system are still amazingly well
preserved and undisturbed.
Besides the obvious question of "WHY?", many
questions remain. Was water hand carried to the mesa
top? What happens at the East End of the mesa where
the terrain simply quits? After miles of carefully controlled
slope, are steep drops inevitable? What leveling instruments
were used for such precision? Why is much of the canal
brim full of fine sand?

They do not seem prehistoric in that there is no
association with potsherds, lithics, fields, or habitation sites.
The rocks also seem to have been moved a significant
distance, most likely by wheeled transport. They also
look "too new".
The nearest 4WD track is 900 feet south and the
property is BLM Rangeland. Expanations of rifle
range backdrops, scouting projects, erosion control,
cattleguards, hoaxes, movies or vid commercials, kids
pissing around, drug dealers, UFO landing sites, or
rancher improvements all seem unlikely. There are
no obvious trash artifacts, modern or otherwise.
I am at a loss to explain these. The simplest thing
is to blame them on the CCC. Who have proven
adept at doing totally useless stuff in strange ways.
Nearest CCC camp was 8 miles away at Noon Creek.
The artifacts do not show on available images.
A tiny bit of supporting evidence is that some of
the rock arrangements show "Italian stone masonry"
careful arrangement and placement quite similar to
those of other known CCC sites. No concrete is used.

West Peak Lookouts, and the Colombine Ranger Station.
Larger spillways in Fort Thomas and Eden appear to have
long been breached or rendered useless.
Projects that appear worthless to me do include
the entire rock city at Sanchez and many hundreds of
serpentine check dams that seem to me to be of no use
whatsoever. Supposedly, these were "water spreaders
for water infiltration". I'd guess that virtually all of the
water simply evaporated. Some of these exhibit exceptional
quality stone masonry work.
For some strange reason, landfills remediated

constructs from legitimate prehistoric water control

There are many rock structures here in the Gila valley.
Some of these are prehistoric indian agricultural work,
and some are CCC busywork projects from the 1930's.
Telling which from what can create problems. Here are
a few guidelines...
CCC projects tend to be anal. Prehistoric projects tend
towards zen and in harmony with the land..
CCC projects are often obvious on satellite photos.
Prehistoric projects are usually subtle or invisible.
CCC projects are usually linear. Prehistoric projects are
often associated with grids, fieldhouses, cairns,
or roasting pits..
CCC projects may have obvious modern features
such as survey markers, railroad rails, concrete,
wire grids, or integrated wide farm roads.
Prehistoric projects may have lithics, trincheras, or
checkdams with aprons associated with them.
But potsherds are often rare at an ag site.
CCC projects tend to be wider, with three to
four feet being typical. Stones are often
precisely fit "masonry style" with tight
tolerances and well defined project edges.
Some CCC projects tend to be crisp and
pristine. Prehistoric projects tend to show their
age and are often partial or ill defined. Or
show flood damage.
Prehistoric projects usually use nearby rocks. CCC
projects may truck or otherwise import different
rock styles from remote areas.

I thought I was fairly familiar with our local Marijilda Canal
system. Which I had wrongly been crediting to early farm
pioneers in the 1800's. Turns out it was a small part of a much larger
and more complex native american system dating from the 1300's.
Apparently they simply stole the plans.
I just received a portion of a yet to be published paper and map
of this original system. It is clearly one of the more stunning of
many early Gila Valley water projects.
Firstoff, the origional system was at least 12.5 kilometers
( or nearly eight miles ) long! It was designed with cutoffs
so that any catastrophic flood would completely miss nearly
all of the system except for an easily repaired head end.
Amazingly, there was an aqueduct or "above grade" portion
where the canal crossed a drainage. And a fairly long
"cliff hanger" portion where the canal was literally stuck
high on the side of a steep mesa.
Finally, the far end of the canal ended in a large loop.
Exactly why it does so is a mystery, since any canal
( especially a prehistoric one ) has to have a gradient
to deliver useful amounts of water.
Portions of the canal system remain remarkably well
preserved. I'll try to post a better reference when the
paper becomes available.

Our ancient grid systems here in the Gila Valley
are much more extensive than most people even imagine.
Besides highly concentrated northern grids, there are
many isolated and smaller examples to the south. Typically
these are gently sloping near mesa tops in areas with
bunches of loose rocks in the 2 to 10 pound class. The
rocks are typically rounded river cobbles and are not
worth a damn as higher wall construction materials.
Several classes of rockwork are apparent...

singly or in groups. In a somewhat erratic
Round rockpiles perhaps three feet in
diameter. Some with internal depressions.
Arc shaped check dams across small
drainages, some with distinct downstream
These tend to be well away from habitation sites of
multi room ruins. Potsherds are almost entirely
absent, and lithics are somewhat scarce.
Some of these are masked by more modern
structures such as early Mormon irrigation canals,
CCC projects and even modern rock walls and
rearrangements. In general, the CCC projects are
far more anal and precise. But proper attribution of
simpler structures remains a problem.
My latest discovery is a linear feature that extends
nearly a mile and exactly follows a constant elevetion
topo contour. Calling it a "canal" is premature and it is
not at all obvious what the water source or its destination
was. There seems to be no modern interest in the area.
Aerial and satellite photos are maddeningly infuriating
because their resolution is way too low. Their copy
protection features are easy to misinterpret as well.
A few more details here.

Our local "Southern Grids" area has an incredible
variety of prehistoric grids, roasting pits, ruins,
trincheras, and such. Some of which are covered
Trouble is that the same area has great heaping
bunches of CCC water control projects. And the
two can easily be confused. More to the point,
it is difficult to accuratly guarantee any particular
simpler construct is in fact prehistoric.
In general the prehistory folks had more potsherds
and lithics. And were much more in tune with nature.
The CCC was far more anal and rectangular. Plus
may have included obvious survey markers or
chunks of railroad rails. Some structures obviously
had an Italian stone mason as a foreman. With
transit accuracy and one inch tolerance.
Sometimes deciding whether you are looking at one
or eight centuries worth of erosion can help. On
lesser features, the distinction is far from obvious.
A further confusion is that depressions attributed to
Mescal roasing pits could in fact have been natural
and caused by the hugely trunked mesguite trees once
in the area. Almost always, though, a depression in
any non-karst area is man caused.
Enigmatic are the check dams with downsteam
aprons. At present, these appear in use by both cultures.
one possible explanation is that the CCC liked what they
saw and simply stole the plans.

As any geologist will tell you, there are three
kinds of rocks: Ingeneous, Sedentary, and Metaphoric.

While Black Range Lodge remains my favorite
bed and breakfast because of long term friendships,
I can also highly recommend Casitas De Gila.
Casita's highlights include remote hot tubbing under
the stars in one of the finest dark sky locations in
the country, a bunch of easy new riparian stream trails,
a superb mini art gallery, free WiFi, panhandling horses,
and acess to a group of telescopes and terrestrial optics.
The two B&B's are an easy two hour trip apart. Both are
in the parts of New Mexico you can't get to. With superb
stuff in between to visit. Stop off and buy our wilderness
property while you are on the way.

One of the real dangers of attempting humor in any
public or semi-public form is "them" not getting the joke.
I was recently appalled at a failed humor attempt when nobody
in the audience had the slightest idea who Dilbert was!
One glance at our local rock grids dating from the 1300's
and their astonishing similarity to the Dilbert cubicals jumps
right out at you.
In fact, If I took my Marcia Swampfelder skills and
combined them with a one time ability to sling the shit
on anthro papers, I bet I could come up with a credible
peer reviewed paper that these were in fact the prehistoric
This would take no more of a leap of faith than most
other archaeological papers routinely make.
Meanwhile, free Dilbert movies are offered here.

A digital camera optimized for Draganfly
use could be made ridiculously lighter, smaller,
and less power hungry than an ordinary one.
But whether the quantities would justify the
engineering is another matter entirely.
Firstoff, you would get rid of the "Heinz
Catsup Bottle" effect and make no attempt
whatsoever to make the design look like a
classic 35 mm camera. Fixed infinity focus
will work just fine, eliminating any and all
There would be no need for a LCD display
and its ungodly power gobbling backlight.
Nor for a conventional viewfinder. Much of
the digital signal processing could possibly
be downloaded to the base station. With less
than half of the camera actually in the air.
And you might actually put a dozen or more
of these on a single platform, eliminating the
need for pan and tilt. You simply pick and
power the one that is pointed in a useful direction.
most of the circuitry could be shared, so only
the sensors and lensing would be multiple.
The potential for integrating camera and
platform, power and nav here is enormous.

The Direktor of the Ministry of Propaganda for a
major government bureaucracy sends this along:
“Gila Valley Day Hikes” Topic of
First 2009 Brown Bag Talk
Author and researcher Don Lancaster of Thatcher
will present the first talk of 2009 in the Bureau of
Land Management’s (BLM) popular Brown Bag Lunch
seminar series. “150 Gila Valley Day Hikes” will be the
topic of Lancaster’s talk on Tuesday, January 13, at
noon in the BLM conference room.
The public is both welcome and encouraged to attend.
Bring a lunch or snack and a drink and enjoy the talk
and accompanying audio-visual presentation.
Hikes to be discussed vary in difficulty from easy
walks for families with small children to extreme
canyoneering. Most hikes have recently been verified
for access and conditions.
Anyone that has attended one of Lancaster’s evening talks
at Discovery Park can attest to his knowledge and sense
of humor. When asked what locations will be discussed,
he said “Most hikes are less than an hour’s drive from
the Greater Bonita-Eden-Sanchez Metropolitan Area.”
Lancaster has posted brief descriptions of many of trips on
his website at http://www.tinaja.com/gilahike.shtml.
Places to avoid will also be briefly covered.
The BLM office is located at 711 14th Avenue, at the
intersection with 8th Street, in Safford. For more information,
contact Diane Drobka at 348-4403 or Dave Arthun at 348-4428.

Was looking for come cost effective way to
photograph the Safford Grids, as well as search
for newer ones. Not to mention cave exploration.
Apparently there have been some stunning
improvements in radio controlled model helicopters
One leader in the field appears to be Draganfly.
Their best units appear to be a triangular platform
with six electrical motors, two at each apex. A
complex gyro and computer system makes the
sysstem easily flyable and quite stable.
These remain pricey, but there should be some
lower cost systems evolving from them. GPS
tagging is also newly included.

I've been revisiting some of our local indian
ruin sites. Despite competent researchers,
the Gila Valley has lacked an obvious champion.
Yet its population and influence apparently
were among the highest in the American
The area is confusing to say the least, as
pottery styles represented Hohokam,
Salado, Ancient Pueblo Peoples, Mongollon, and
Mimbres, among others. Clearly complex trading
routes went through the area.
There were elaborate irrigation systems.
Both from the Gila River and riparian
side canyons. Not to mention many thousands
of water enhancing grids that may have been part of
an elaborate aguave to mescal booze factory.
Or possibly the world's very first prehistoric Dilbert
Many of the sites have been outrageously
pothunted. Others have been obliterated by
Modern agriculture has also trashed the tops
of many sites. But they may lie pristinely buried,
awaiting subsurface radar techniques for modern
excavations. When all is said and done, plows do
not normally go all that deep.
Some interesting reading appears here, here, and here.
