How to Read Trees to Find Old Homesites When Metal Detecting

When you’re out metal detecting, you might think the key to finding treasures lies only what the metal detector sees beneath the soil, but there are lots of other things that are a key for a specific site. 

How Trees  “Talk” to Metal Detectorists: Unlocking Hidden Clues in the Landscape

I want to share about the trees around you which can actually be some of your best indicators of old homesites and treasures. Trees silently “talk” to us through their shape, placement, and condition, revealing stories about old homesites, battle sites, farms, roads, and even hidden caches. Learning to listen to these arboreal clues can take your metal detecting game to a whole new level, whether you’re just starting out or have years of experience.

Pillows, Cradles, Pits, and Mounds: Nature’s Tells Beneath Fallen Trees

Have you ever noticed how fallen trees sometimes create weird dips and bumps in the ground? When a tree is uprooted, its roots tear up the soil, disturbing whatever lies beneath. These are called pillows and cradles or pit and mound formations.  For metal detectorists, these spots are golden opportunities. Artifacts might be uncovered naturally or trapped in the pockets left by roots. When you see these natural landforms, it’s worth slowing down, sweeping your detector carefully over both the pillow or cradle, or anything left of the root ball and recovering targets.  Be sure and scan the root ball if present and even the roots where you can.

In history when a farmer cleared the field of trees, he would cut them down, and then he would pull the stump with horses  or oxen.  They would dig all around the roots and cut the roots to make it easier to use poles or animals.  A PRIME area to hunt pillows and cradles is where there were military engagements that are being reshaped into residential areas.  The root balls  on those trees taken out have, in my detecting years, given up minieballs, CW buckles, relics, and even one Hotchkiss shell that I witnessed.

Estimating Age: Trees as Timekeepers of the Past

You don’t need to be a botanist to estimate a tree’s age roughly by its size and growth habits. Older trees can indicate how long an area has been undisturbed or abandoned. For metal detectorists, knowing if a tree has been growing for 50, 100, or 200 years can help date the site. This helps focus your search on the right era’s artifacts, improving your chances of finding historically valuable items.  Here is a method  for aging trees at a site.  It  is a good estimator to use.

Barbed Wire and Trees: Marking Past Boundaries

Old barbed wire tangled in tree trunks is a natural aging marker. It shows where pastures or property lines existed decades ago. For detectorists, these areas are hotspots for relics from farm life, such as tools, horse tack, or discarded hardware. Following these wire-lined tree boundaries is often a good strategy for systematic searching.

The way this ties in to the trees is that trees grow from the top and not the bottom, except in diameter, and they grow there as well regardless of their age.  If wire or relic gets embedded in a tree it will remain at the height of its placement.  So a barbed or horse stranded fence wire in a tree 100 years ago will be at the same place.  By measuring the distance from the outside of the tree to the barbed wire or artifact and deducting that form the diameter factor the growth you can determine how long ago the wire was placed  there.

You can count the number of vertical rings from the outside bark to the bottom of the scar to tell how many years it has been since that farming or logging occurred.Many times it is because at some point in the tree’s past some vehicle or wagon or equipment grazed that tree and damaged the outer bark.  To know how long ago that was,  you can count the number of rings from the outside bark to the bottom of the scar to tell how many years it has been since that logging  occurred.

Cut-Off Limbs: Trees Bearing Scars of Lost Homes

Trees with oddly cut or missing limbs, especially those pointing in a particular direction, are often telling you about an old structure that once pressed against them.  They had the same issues with tree limbs intruding onto roofs as we do back in the day.  Tree limbs would cause holes in the roofing material (and therefore leaks), so the old farmers and ranchers would cut the limb off.  Rooflines, porches, or fences rubbing branches can stunt or remove limbs. These scars act like arrows pointing to former homesites or outbuildings that have long since vanished. When you see these cut limbs, think about expanding your search radius in that direction, as these spots often yield household items, keys, or nails from the past.  In a group of trees that surrounded an old house, these will all point to the location where the house or other building once stood. In the image below you can see such a scar that has healed over the limb or branch collar is what forms that rounded scar.  You can also note on the face of many such old trees like the one below, the saw marks from when the limb was cut off.

Non-Native Trees: Signs Someone Was Here

If you spot a species of tree that doesn’t naturally grow in the area, chances are someone planted it long ago. These “outsider” trees often mark old gardens, homesteads, or orchards. For example, a lone pecan, fruit tree, or ornamental tree in the middle of native woods can be a silent testament to human presence. Practical tip: metal detectorists should investigate these trees carefully—sometimes treasures like coins, buttons, or tools were buried nearby or dropped by residents tending their trees.  As you can see below here, fruit trees typically don’t survive from more than a half century ago.  If there was two or more, they can cross pollinate each other and live on through their seeds.  You can still use them as references IF they are out there.

Fruit tree	Potential lifespan in years
Olive	500+
Mulberry (white, black)	100+
Pomegranate	200+
Fig	50-75
Persimmon	50-75
Apple (full size)	35+
Pear (full size)	35-45
Quince	30-40
Apricot	20-30
Cherry (sweet)	20-30
Cherry (sour)	15-20
Peach	15-20
Plum	15-20

Patterns in the Trees: Lines and Squares Aren’t Accidental

Nature rarely arranges trees in perfect rows or geometric shapes. So, when you find trees set up in a line, square, or other patterns, it’s a strong clue of human design—likely old fence lines, property boundaries, wind breaks, or orchard layouts. For the detectorist, these patterns help map out where structures or fences once stood. You might uncover old fence staples, barbed wire fragments, or even foundation stones hidden by the tree canopy.

Here is a great example of the patterns….ahhh, there are three in this pic…..The smaller one to the right is where a barn or stable was.  This was actually a large rock pen enclosure from circa 1860s where cowboys would bring cattle to get ready for a drive to market.  For scale, the rock pen is 836 ft top to botton and 643 feet side to side.  Trees in any geometrical pattern should always be investigated.

Here below is another great example of trees talking to us about potential metal detecting sites.  A plowed field with a small grove of trees in the middle of the field.  You should always ask why are these types of trees in this or that open field.  This type of site bears examination as it is most likely that there was a house right in those trees and now the remnants of the old farmhouse is still present there.  Note also that there is an area of unplowed field extending out from those trees.  I would suspect  that to be a debris field surrounding those trees, such as concrete, old building materials, pipes, etc.

Roots and Bark: Nature’s Hidden Treasure Boxes

Sometimes, treasures hide literally within a tree. Roots can grow around and trap objects like bottles, coins, or tools, preserving them beneath the surface. Bark carvings or unusual markings might have been left intentionally by past owners or treasure seekers as symbols or messages. A practical tip is to check around the base of unusual or large trees, clearing leaf litter or dirt to reveal clues. Always be careful not to damage the tree while investigating.  By all means if you see a hole in a tree close to a nearby old homesite, have a look with your detector and if possible with your eyes (your cell phone is a handy device to take a picture down in a hole)

Barbed Wire and Trees: Marking Past Boundaries

Old barbed wire tangled in tree trunks is a natural aging marker. It shows where pastures or property lines existed decades ago. For detectorists, these areas are hotspots for relics from farm life, such as tools, horse tack, or discarded hardware. Following these wire-lined tree boundaries is often a good strategy for systematic searching.  This following chart shows the different forms of barbed wire and the year it came to market.  This in turn gives you an idea of how old a site is potentially.

Shade Trees: Natural Rest Stops for Past People

Big shade trees near old roads, wells, or fields were natural gathering points for workers or travelers needing rest, food, or water. These spots often harbor dropped personal items—coins, pocket knives, or buttons. If you’re out hunting on a hot day, these shady trees may offer more than just rest; they can be clues to where people once stopped and left traces behind.  A GREAT place to look is a shade tree adjacent to or nearby a grist mill.  People who came to have their corn or wheat or oats milled would bring their crops to the miller who usually took a percentage for pay, or cash.  People would all be there with their crops and it might well take several trips to get it all done.  A day of bringing grains to be milled was a hot day from all the work involved.  Many of the mills were along a river or creek and were run by water.  And along with the water would be trees.  A nice big shade tree offered respite from the heat as they waited their turn.  There could be talking, eating or even gambling.  Trees located close to the site of a grist mill are one of my favorite areas to hunt when hunting such a site.

Lining Roads and Railroads: Trees as Living Markers

Many old roads and rail lines were intentionally lined with trees to guide travelers or prevent soil erosion. Recognizing these living markers lets you trace historic transportation routes where lost or discarded items may accumulate. Walking these tree lines with your detector can uncover coins, tools, or even lost valuables dropped by passengers or workers.  Trees were also used to create what is called  Corduroy roads.  They were laid down perpendicular to direction of travel and were used in boggy or muddy areas by the military.  This translates of interest to us because if you are in a low lying area and see trees lined up next to each other, they are there for a reason. Muddy areas and swampy areas where they were used have survived until modern times.  So be vigilant!  Here’s some modern day remnants of a corduroy road.  The takeaway on this is that the workers may have lost relics or even money building these roads. 

Indian Bent Direction Trees: Pointing the Way

Some indigenous peoples shaped young trees by bending them intentionally to mark trails, water sources, or special sites. These “bent trees” are often subtle but powerful directional signs. Spotting and interpreting these can lead you to ancient campsites or sacred grounds, rich with artifacts and history. They always point the way to a significant place, such as a water source, and sometimes you can follow them until the direction you go in finds another direction tree.    Below is an example of a bent Indian direction tree  This particular tree leads to an old spring used by settler in travel and pioneers along with the Native Americans.

Water Indicators: Willow Trees and More

Certain trees like willows only grow near water, signaling creeks, springs, or wetlands. Water sources have always been magnets for people, so these trees hint at locations where camps or settlements may have existed. For metal detectorists, searching near these water-loving trees is smart because artifacts like fishing gear, tools, or lost personal items often accumulate near water. Settlers, Indians, Cattle drives, military, wagon trains and just travelers passing by would stop at water.   You should learn the trees in your area.

Here is a list of trees that can tolerate wet soil and/or standing water:

Atlantic White Cedar Bald Cypress Black Ash Freeman Maple Green Ash Nuttall Oak

Pear Pin Oak Plane Tree Pond Cypress Pumpkin Ash Red Maple

River Birch Swamp Cottonwood Swamp Tupelo Sweetbay Magnolia Water Tupelo Willow

Post Hole Banks From Trees

My third cache I found was a post hole back.  The post was laid over on the ground, but had the classic visual clue of nails bent over which allowed the wire to be pulled out of the way to pull out the post.  Trees contributed to that find as well.  Cedar Trees here in Texas have long been used to make fence posts out of.  If you are hunting and you find an old post made from a tree, look at the nails or staples to see if they are cut in such a way to make it possible  to easily remove wire from the post and thus allow the post to be lifted up.

Other Indicators in the Forest to Watch for as Potential Metal Detecting Sites

Wrapping it Up:

By learning to read these arboreal messages from trees, metal detectorists can unlock a deeper understanding of the landscape and the stories it holds. Trees don’t just shade us or beautify the outdoors—they communicate history and guide the savvy seeker’s path to hidden treasures. Next time you’re out detecting, pause and look up, around, and beneath the trees—they may be telling you exactly where to dig.  And IF you live around Weatherford, Texas and see a “Z” carved into an old Oak Tree, there is a cache of silver dollars beneath that Z.  You’re welcome!
