Jaramillo Creek is a 10 mile long stream in New Mexico with headwaters in the Jemez Mountains.[1] Jaramillo is a tributary of the East Fork Jemez which is then a tributary of the Jemez River, a tributary of the Rio Grande. The creek is located in a graben in the Pleistocene age Valles Caldera.[2] The Jaramillo normal event (1.06-0.9 Mya) of the Matumaya Reversed Epoch was named for rocks selected and aged at the type locality near the creek.[3]
