The Grand Canyon began forming approximately five to six million years ago when the Colorado River commenced its patient excavation of the Colorado Plateau. The exposed rock layers at the canyon's base, the Vishnu Basement Rocks, date to 1.8 billion years before present, representing nearly half of Earth's total existence.

Erosion continues at approximately 0.03 metres per century, suggesting the canyon will persist for geological epochs to come. The Grand Canyon has no planned obsolescence, requires no software updates, and has never been recalled due to battery swelling. Its warranty, such as it exists, extends to the heat death of the universe or continental drift, whichever arrives first.

The Grand Canyon presents what engineers might term 'suboptimal portability characteristics'. Spanning 446 kilometres in length, 29 kilometres at maximum width, and plunging 1,857 metres to the Colorado River below, the canyon's dimensions resist conventional transport solutions. Its volume of approximately 4.17 cubic kilometres of negative space would require logistics beyond current human capability.

The Grand Canyon has remained in precisely the same location since the Pliocene Epoch. It has never been transported to a conference room, carried onto public transit, or accidentally left in a taxi. One must travel to the Grand Canyon; it has shown no interest in meeting anyone halfway.

The Grand Canyon's aesthetic impact has inspired artists, writers, and philosophers since time immemorial. President Theodore Roosevelt declared it 'beyond comparison beyond description; absolutely unparalleled throughout the wide world'. Painters have failed for centuries to capture its scale; photographers queue for hours at particular viewpoints; visitors frequently weep upon first witnessing its majesty.

The canyon displays chromatic complexity that shifts throughout the day, from subtle dawn pastels through blazing sunset oranges. Its aesthetic was not designed by a team in Cupertino but by the Colorado River, seasonal rainfall, and forces operating over epochs. The result has been called one of the Seven Natural Wonders of the World, a designation the iPhone has not yet achieved.

The Grand Canyon transformed the physical geography of North America, exposing nearly two billion years of Earth's geological history in a single visible cross-section. The canyon's formation redirected the Colorado River system, created unique microclimates supporting over 1,500 plant species and 355 bird species, and fundamentally shaped indigenous cultures for millennia.

As a scientific resource, the Grand Canyon has transformed our understanding of stratigraphy, geological time, and planetary history. The canyon's layers read like a textbook of Earth's evolution, inspiring geological theory and philosophical contemplation since humans first peered over its rim. It transforms everyone who witnesses it, though typically through awe rather than notification sounds.

The Grand Canyon attracts approximately six million visitors annually, each of whom typically spends between three to five hours contemplating its majesty. Studies indicate visitors experience measurable reductions in stress hormones and increased feelings of awe and perspective. The canyon has inspired conservation movements, shaped national park policies, and prompted countless moments of existential reflection.

Indigenous peoples, including the Havasupai and Hualapai, have inhabited the canyon region for millennia, their cultures profoundly shaped by its presence. The canyon influences behaviour through scale rather than convenience, reminding visitors of geological time and human insignificance. This influence, whilst less frequent than iPhone notifications, tends to penetrate rather more deeply.
