![]() NPS photo/Adrienne Fitzgerald The Springdale Sandstone is considered to be a sub-unit or member of the Kayenta Formation, and was deposited by a main river channel associated with the same river system responsible for the deposition of the Moenave and Kayenta formations. The Springdale Sandstone is visible in lower Zion Canyon as the prominent reddish cliff band above the canyon floor, separating the lower Moenave layer from the rest of the Kayenta Formation.
