It has the resemblance of the natural phenomenon of Antelope Canyon Caves in Arizona, USA. According to scientists these are the result of many millennia of weather extremes, and these canyons were thereby formed over thousands of years of flash flooding of the intermittent creek running through it, wearing away the Navajo sandstone rock-face before emptying into the Colorado River and currently into Lake Powell. At the times of long periods of drought, windblown sand would polish the narrow slot walls into a striated, swirling finish. In this place there seems to be an ever-changing play of light upon its walls and the flowing sandfalls that cascade into the depths of the slot canyon. In this artwork patterns like these natural phenomena have been reflected and shown in such a way like those are carved on a big heavy block of gold being displayed on a large wall of gold in a museum. - A decorative block of gold.
