Fruitland Formation the Colorado-New Mexico state line, and is one of the most productive areas for coalbed methane in the United States. The Fruitland is underlain by the Pictured Cliffs Sandstone, and overlain by the more recent Kirtland Formation. The sequence of rocks represents the final filling of the Cretaceous seaway. The underlying Pictured Cliffs is a marginal marine sandstone, deposited in an environment similar to offshore barrier islands of the southeast United States.

Also running past the rocks are the Heller Ridgeway ("Hellerhöhenweg", waymark "H") and Siegerland High Ring ("Siegerland-Höhenring").
