Standing at 13,517 feet, Trinchera (“trench”) Peak is the northernmost thirteener in the Culebra Range of the Sangre de Cristos.
Trinchera Peak is located near Cuchara where the Culebra Range of the Sangre de Cristo Mountains creates a north striking ridge. This ridge formed when flat lying sandstone strata were thrust into a vertical orientation by uplift, faulting, and block rotation events dating back to the mid-to late Miocene.
