Foster ranch, went to check on his sheep one morning after a series of severe thunderstorms. He was concerned about the wellbeing of his cattle because he heard a very loud explosion the night before during the storm. Upon riding out to the pastures, Brazel discovered a huge amount of strange debris scattered across the fields. Not knowing what this strange debris was, Brazel gathered some of it and showed it to his friends…

    Atahualpa At Cajamarca Research Paper

    By capturing Atahualpa at Cajamarca, the conquistadors had essentially defeated the Incas. Without its leader, the rest of the empire fell easily. Pizarro demanded a massive ransom for Atahualpa, consisting of an entire room filled with silver and gold. He then executed him, replacing him with a puppet ruler. Although several rebellion attempts occurred over the next 40 years, all were unsuccessful, and the Spanish finally colonized the region in 1572 as the Viceroyalty of Peru.…

    Teotihuacan Murals

    This whole paper started with an amazing trip to the Denver Art Museum. The Teotihuacan section immediately caught my attention. This is where I discovered the “Mural of Xochipilla”. Had I known in the beginning how mysterious this piece of art was I would have moved on to another topic for this research paper. Many hours were spent trying to find information on the “Mural of Xochipilla” which yielded no information at all. Not even the museum could reveal anything about the mural except that they had purchased the mural in 1967. While doing the research I was inspired by Teotihuacan’s mysterious culture, which kept me looking for more information. Al though there was no information on the “Mural of Xochipilla”, there seemed to be overwhelming information on the Culture of Teotihuacan.…

    Showdown In The Sonoran Desert Analysis

    The book Showdown in the Sonoran Desert by Ananda Rose was written to bring to light the issue of morality that underlies the controversial immigration debate, particularly the issue of immigrant deaths along the desert of Mexico and the United States. Hundreds of migrants, in an attempt to cross into the United States, lose their lives in the rough environment of the desert. As American citizens, many who are of Hispanic descent are forced to support one side or the other of the controversial debate. Either we support the federal law which rejects any action supporting or aiding an illegal immigrant or we dismiss the law and aid those immigrants in need to prevent possible deaths. Most Americans when faced with such debate, will most likely…

    The Grand Canyon: Geology

    The first layer of sediment dating back 250 mil years ago existed during a time where the area was submerged in water. This is evident by its Kaibab limestone formations and marine animal fossils. Going a layer down we find evidence of what the GC was like 260 million years ago. Cocoino sandstone shows evidence that the Grand Canyon was above sea level with footprints of vertebrate animals confirming. If we go further, we start uncovering 265 million year old Hermit shale and land dwelling animal fossils. This shows during this time the grand canyon was still above sea level. Go another layer down and we hit the 285 million year old Supia Formation. This layer was a mix of both sheals and limestone's which makes it hard to tell weather or not it was or was not above sea level. However, due to the larger amounts of limestone scientists believe it to be more of a marine layer. The next layer is around 320million years old. Its a layer of Redwall limestone that is roughly 500ft high and typically drops at a 90 degree angle. This layer, due to its limestone nature and fossil content was created during a time of submergence. The next three layers make up the layer grouping labeld as the Tonto Group. The youngest layer of this group is The Mauv limestone formation, found below redwall limestone and they too were created while underwater. Trilobite fossils are abundant here. below the Muav we find a layer of Bright Angle Shale signifing the grand canyon was abouve sea level…

The names refer to complex of the rock shelter that was occupied about 10,000 years ago. Evidence found from early maize agriculture. Excavations in the 1940’s at the cave created rich deposits of small early looking corn cobs. Showing that the period gives some idea as to how deep into the antiquity maize was harvested and consumed in the Southwestern America. A similar piece of charcoal gives date before 6000 B.P (years before present). Archaeological have also uncovered proof that the corn (popcorn) had been around long before Europeans arrival to the New World. The cave became a gate way in the north that was a broaden of corn, beans, and squash. Later findings would revile that it was an indigenous gourd and not a squash. Findings would also include stone artifacts of human inhabitation spanning 5,000 years ago.…
