Accepting the Narrative

Much of what you were taught in school is wrong. James Loewen documented this extensively in Lies My Teacher Told Me, showing how American textbooks routinely distort, omit, and sanitize the past. That pattern doesn’t stop at textbooks. It extends to the land beneath your feet.

When we look at the American Southwest today, we assume we are seeing something ancient, a desert shaped by deep geologic time. Much of what we now call “desert” isn’t ancient at all, but the result of only a few hundred years of human activity.

Inside the Copper Queen Mine in Bisbee, Arizona, a timber support beam nearly 5 feet in diameter still stands, marked as having been cut outside. This beam exists in a region we are told has been desert for all of human history. The mining operations that followed consumed forests at an industrial scale. Estimates suggest the Bisbee mines alone devoured 3,000–4,000 square miles of forest, roughly the combined area of Phoenix and Tucson. Early photographs show hills stripped to bedrock, a moonscape later mistaken for a natural desert environment. This pattern wasn’t isolated to the USA. Baja California’s forests were stripped to fuel steamships carrying smelted ore back to the eastern seaboard, leaving behind a landscape now assumed to have always been arid.

Nearly all of Arizona’s major rivers once flowed year-round. For anyone outside the state, that sentence alone should be jarring. The Gila was once navigable by large riverboats. Indigenous accounts describe shaded corridors and fertile banks, while pioneer journals describe arm-length fish so dense in the rivers that horses killed them with their hooves simply by crossing. A Texas cattleman admitted that Tucson was lush and heavily vegetated until only a few seasons of his own cattle “trampled it into ruin.” Overgrazing hardened the soil, killed infiltration, and destabilized waterways. Invasive tamarisk followed. Millions of beavers were exterminated for fur, erasing the dams and wetlands that once regulated aquifers. Springs failed. Water tables collapsed. Dams and diversion projects completed the transformation.

Even in the 20th century, the erasure continued. Near South Mountain in Phoenix AZ, an ironwood forest once stood with canopies so broad that people remembered driving vehicles beneath them. That ecosystem died when the Salt River was rerouted. On Mount Lemmon above Tucson, a Forest Service plaque still records that pines and firs once grew far down the valley floor. What we now call desert scrub was forest within living memory.

Along California’s coast, continuous forests once pulled storms inland. Shoreline forests and Offshore kelp forests seeded clouds that fed moisture deep into the interior, reaching as far as Nevada. Remove those systems, and the hydrological engine collapses. Nevada didn’t become extreme by fate. It became harsher because the systems that once softened its climate were dismantled. Hydraulic mining added its own scars, blasting mountains into artificial mesas and flattened buttes, many of the same “natural” formations we photograph today. These wounds resemble geological features closely enough that most people never question their origin.

The same arc appears globally. In the Middle East, the cedars of Lebanon once blanketed the hills. Mesopotamian forests fed temples, ships, and war machines. The Fertile Crescent didn’t begin as desert. It became one. The Sahara was a green world of rivers, lakes, grasslands, hippos, and crocodiles only 6,000 years ago. In Australia, coastal forests were stripped to supply British shipbuilding, which consumed upwards of 3,000 mature trees per warship, collapsing rainfall patterns across the interior. In Europe, Santorini and the surrounding Greek islands, now assumed to be naturally barren, were once densely forested. Archaeobotanical evidence from Akrotiri shows pine, oak, juniper, and cypress before the Bronze Age. These forests were cut for fuel, metallurgy, and shipbuilding. The volcanic eruption finished what deforestation began. Plato himself wrote that Attica once held forests as abundant as Macedonia, but by his time only “the bones of the land” remained.

Break the forests. Break the rivers. Break the hydrological cycle. Then forget it was ever different.

The world we think we know is already wrong after only a few hundred years. If it is this easy to erase something that happened in the modern era, with photographs, written records, and living witnesses, ask yourself how confident you really are about what happened before any of that existed.

If landscapes can be rewritten in centuries, timelines can be rewritten in generations. And nowhere has that rewriting been more consequential than in how we date the Earth itself.
