  • Origin of Non-Bedded Pyroclastic Rocks in the Cathedral Cliff Diatreme, Navajo Volcanic Field, New Mexico
    The following document is a pre-print version of: Bélanger C, Ross P-S (2018) Origin of nonbedded pyroclastic rocks in the Cathedral Cliff diatreme, Navajo volcanic field, New Mexico. Bull. Volc. 80:article 61, DOI 10.1007/s00445-018-1234-0 Origin of non-bedded pyroclastic rocks in the Cathedral Cliff diatreme, Navajo volcanic field, New Mexico Caroline Bélanger*, Pierre-Simon Ross Institut national de la recherche scientifique, 490 rue de la Couronne, Québec (Qc), G1K 9A9, Canada * Corresponding author. E-mail addresses: [email protected] (C. Bélanger), [email protected] (P.-S. Ross) Keywords : Diatreme, non-bedded pyroclastic rocks, phreatomagmatic, Navajo volcanic field Abstract Cathedral Cliff is a well exposed mid-Tertiary phreatomagmatic diatreme in the Navajo volcanic field, New Mexico. Post-eruptive erosion, estimated between 500 m and 1000 m, exposes the deep part of the diatreme. Cathedral Cliff provides an opportunity to examine the transition between the bedded pyroclastic rocks of an upper diatreme, and the non-bedded pyroclastic rocks of the subjacent lower diatreme. Bedded pyroclastic rocks occupy 49% of the mapped diatreme area, non-bedded pyroclastic rocks occupy 45%, and the remaining 6% consists of sedimentary megablocks. The bedded pyroclastic rocks range from coarse tuff to medium lapilli tuff, and from lithic to juvenile rich. They were emplaced during eruption at the bottom of the crater by pyroclastic density currents, pyroclastic fallout, and as ballistic bombs and blocks. As the eruption continued, they subsided into the diatreme to their current location. Bedding ranges from well-preserved (“continuous beds”) to partially destroyed (“broken beds”).

The testing was designed to determine the nature and extent of the sites and see if a data recovery program was necessary. NMSHTD proposes to construct a six foot shoulder on both sides of NM 134 in San Juan County. The initial survey was performed by NMSHTD archaeologist Sandra Marshall and Office of Archaeological Studies (OAS) archaeologistAnn Noble on August 28 through September 9, 1988. Limited archaeological testing was conductedby OAS archaeologist Dorothy Zamoraffom July 24 through August 24, 1989, under ARPA Permit ARPA-89-002and Navajo Nation Permit (28904. Testing at LA 68377 produced a calibrated radiocarbon dateof 5070 f 190 B.P., dating the site to the Archaic period. LA 68378is a collapsed Archaic rockshelter witha calibrated carbon-I4 date of 2790 f 170 B.P. LA 68379 isa historic sitedating between 1930 and 1940.

  • The Navajo: a Brief History
    TheThe NavajoNavajo: A Brief HistorHistory:y According to scientists who study different cultures, the first Navajo lived in western Canada some one thousand years ago. They belonged to an American Indian group called the Athapaskans and they called themselves "Dine" or "The People". As time passed, many of the Athapaskans migrated southward and some settled along the Pacific Ocean. They still live there today and belong to the Northwest Coast Indian tribes. A number of Athapaskan bands, including the first Navajos, migrated southwards across the plains and through the mountains. It was a long, slow trip, but the bands weren't in a hurry. When they found a good place to stay, they would often live there for a long period of time and then move on. For hundreds of years, the early Athapaskan bands followed the herds of wandering animals and searched for good gathering grounds. Scientists, believe that some Athapaskan bands first came to the American Southwest around the year 1300. Some settled in southern Arizona and New Mexico and became the different Apache tribes. Apache languages sound very much like Navajo. The Navajo Athapaskans settled among the mesas, canyons, and rivers of northern New Mexico. The first Navajo land was called Dine’tah. Three rivers - the San Juan, the Gobernador, and the Largo ran through Dine’tah, which was situated just east of Farmington, New Mexico. By the year 1400, the Navajos came in touch with Pueblo Indians. The Navajos learned farming from the Pueblo Indians and by the 1600s, they had become fully capable of raising their own food.
