Question

Why is the Redwall Limestone important?​

Answer 1

The Redwall Limestone is one of the most distinctive and prominent formations within the Grand Canyon. It characteristically weathers into an unbroken vertical cliff more than 500 feet high, stained red from the overlying Hermit and Supai formations.

It is susceptible to much solution activity by groundwater and has produced numerous caves, solution caverns, arches, and springs within the canyon. In several places these solution features give rise to a number of important springs like those of Vasey's Paradise, where large quantities of water can be seen issuing forth from springs high on the cliff face midway in the formation.
