[3] The Mogollon-Datil volcanic field was formed in "four discrete pulses representing synchronized activity of two separate cauldron complexes".

[4] The volcanic activity of the Mogollon-Datil began near present-day Las Cruces, New Mexico about 36.2 million years ago (mya) with the eruption of the Cueva Tuff from the Organ Caldera.

Still further south, voluminous volcanic activity in northern Chihuahua took place in this time period and no lacuna exists.

[9] Clasts of the Vicks Peak and La Jencia Tuffs have been found in the gravel beds of the Benavidez Member of the Cerro Conejo Formation in the Rio Puerco valley west of Albuquerque.
