A three-sided, pyramid-like structure initially spotted in 2002 within Mars's Candor Chasma has garnered recent attention after being shared on social media. Despite claims suggesting an artificial origin, scientific analysis indicates it is a natural geological formation.
Discovery and Documentation
Images of the structure originated from NASA orbiters. Its earliest documented identification was by independent researcher Wilmer Faust in a 2002 Mars Global Surveyor image. Subsequent high-resolution images from the HiRISE camera on NASA's Mars Reconnaissance Orbiter have provided further details.
Geological Context in Candor Chasma
When viewed in the context of its surroundings, the structure appears consistent with other geological features in Candor Chasma. This canyon, one of the largest on Mars, was shaped by water, landslides, wind, and possibly tectonic activity over billions of years. The region features numerous "positive relief knobs," which are durable rock structures left standing after softer surrounding bedrock eroded away.
The Candor Tetrahedron: Size and Earthly Parallels
The Candor Tetrahedron, approximately 290 meters in diameter and 145 meters tall, fits the description of these knobs. Similar natural pyramid-shaped mountains exist on Earth, such as Cerro Tusa in Colombia and formations in China's Guizhou province.
Evidence Against Artificial Origin
Close examination of the Martian structure reveals it sits among aeolian ripples, indicative of ongoing wind erosion.
Its ridges are uneven and its three sides are not geometrically perfect, characteristics inconsistent with artificial construction.
This phenomenon is often attributed to pareidolia, where humans perceive patterns or familiar shapes in random data.
