GEOLOGICAL ORIGINS

Formed 200 million years ago

Created as waves of sand dunes were deposited over an extremely dry period

The dunes were then deposited to depths of up to 1,000 feet

Over the next 100 million years, the formations were buried by an additional 5000 feet of strata

These pressures then consolidated and hardened the rock of the formations.

HUMAN HISTORY

• Rainbow Bridge for many decades has been believed to be a sacred religious site for American Indians. Some of the American Indian religions consider arches and bridges to be gateways through which souls enter or leave the earth. Presidents were also effected and touched by this national monument.

• The reason why we should protect Rain Bridge is because Navajo belief suggests that Rainbow Bridge is a symbol of deities responsible for creating rain, the essence of life in the desert. We should protect it for its cultural purposes, its importance to Navajo culture and also its aesthetic purpose it serves to all people who visit it.
