The Moenave Formation is an early Jurassic formation that is found in Southen Utah. It is at the foundation of Zion National Park and can be seen many places through out St. George and the surrounding southern Utah. The Moenave Formation consists of thin layers of reddish-brown sandstone, siltstone, and varicolored mudstone deposited in streams, floodplains, and lakes from over 200 million years ago.  The formation is closely related in age and deposition to the Wingate formation found near Moab and Canyonlands.

It is pronounced "Mo-in-ah-vey."
