The '''Cutler''' is a rock unit that is spread across the [[U.S. states]] of [[Arizona]], northwest [[New Mexico]], southeast [[Utah]] and southwest [[Colorado]]. It was laid down in the [[Permian|Early Permian]] during the [[Wolfcampian]] stage. In Arizona and Utah it is often called the '''Cutler Group''' but the preferred [[United States Geological Survey|USGS]] name is '''Cutler Formation''''.<ref>[ GEOLEX database entry for 'Cutler'] Accessed 18 March 2006</ref> Its subunits, therefore, are variously called formations or [[member (geology)|member]]s depending on the publication. This article will use the national standard set by the USGS. Members (oldest to youngest [age sorting needs to be checked]):
*Elephant Canyon (Utah)
*Halgaito (Arizona, Colorado, New Mexico, Utah)
