These rocks lack Cenozoic volcanic detritus and their youngest zircon are Triassic in age. The depositional age is probably late Cretaceous or early Cenozoic, but it's uncertain. This is the record of what was sitting at the earth's surface following Mesozoic, Sevier-era shortening. It's overlain by the Eocene Elko Formation. https://images.squarespace-cdn.com/content/v1/577fd7412e69cfdc8fbeb0d9/1468188347308-SGLITVVTK5TJDZF4IA7A/IMG_0219.jpg Images - Thunderstorm over the Ruby Mountains Standing at the top of Cedar Ridge looking east across Huntington Valley toward the Ruby Mountains. https://images.squarespace-cdn.com/content/v1/577fd7412e69cfdc8fbeb0d9/1468188355990-US7V1CMR3G7OC5JT2S4E/IMG_6713.jpg Images - Tuff of Dixie Creek, Huntington Valley, Nevada https://images.squarespace-cdn.com/content/v1/577fd7412e69cfdc8fbeb0d9/1541108473373-W3P4BQ5KEPGCISJN5H7G/image-asset.jpeg Images - Jens-Erik Lund Snee, U.S. Geological Survey Earthquake Science Center Seminar talk https://images.squarespace-cdn.com/content/v1/577fd7412e69cfdc8fbeb0d9/1468188358595-V6ZMKD3CZCWV0J447BZ0/IMG_6712_2.jpg Images - Huntington Valley, Nevada https://images.squarespace-cdn.com/content/v1/577fd7412e69cfdc8fbeb0d9/1468188350241-8E89E4WHYJOTL230R8IZ/DSCN1837.jpg Images - South Island, New Zealand https://images.squarespace-cdn.com/content/v1/577fd7412e69cfdc8fbeb0d9/1468188344806-IXIPDVZS36GNZAKSDOG0/IMG_0248.jpg Images - Piñon Range, Nevada https://images.squarespace-cdn.com/content/v1/577fd7412e69cfdc8fbeb0d9/1468188352040-PO5LHX8121JIRQSWYKJ4/DSCN1812.jpg Images - Smithy Creek fault, South Island, New Zealand See Lund Snee et al.
