The inhabited history of the Las Vegas Valley stretches to 23,000 b.c. , when much of the area was covered by a prehistoric lake. During this period, the indigenous people lived in caves, hunting the mammals that gathered at the shoreline. The landscape of the valley changed dramatically over the next 200 centuries. The glaciers feeding the lake melted away and the lake evaporated. Fossils tell an obscure story of man's slow and sporadic development. Around 3000 b.c. , native Archaic Indians began to develop a lasting hunting and gathering culture. By this time, the valley was in much the same geographic state as it exists in today, with one exceptionthe presence of artesian springs that bubbled to the surface in several areas. These springs fed a network of streams draining through the Las Vegas Wash to the Colorado River. The areas surrounding the springs were desert oases: sprawling collections of grasses, trees, and wildlife. Many springs lay in areas that would eventually become the center of the modern Las Vegas metropolis. For about 4000 years, the Archaics thrived in a culture that included many signs of early civilization. Signs of even more advancement appeared halfway through the first millennium a.d. , when the Anasazi Indians inhabited the valley. Far more progressive than the Archaics, the Anasazi utilized such formal agricultural techniques as irrigation to assist their harvest. This permitted the Anasazi to achieve a benchmark of advanced societythe ability to live in permanent shelters year-round without need to follow wildlife. Mysteriously, the Anasazi vanished from the valley around a.d.

Was agriculture and forms early civilization available at any point in Las Vega's history?

Allan crouched over his desk once more, pen in hand and mind blank. He contemplated a story, an outline he had laboriously constructed some time ago. He had filled his pen and raised it, the nib descending towards the paper, before the sound came: the gentle, persistent tapping of the gnarled, primeval willow touching the window with long, insistent fingers. His eyes awoke with a passionate, determined flame, though the only light came from the glutted moon. Allan filled page after page, the words escaping from his mind onto the paper. Where before they had marched in regiments, practiced in ranks and followed their leaders' commands, the words now escaped in their true forms, unhindered by any stricture. He continued long into the night, until the eldritch orb had sunk into the waiting hands of the willow, raised perpetually skyward. Arthur looked up from the results of a night's frenzied labors and looked Allan in the eye. "What is this?" he queried, indicating the pages he held in his left hand. "I decided that since I wasn't having much success with more traditional stories, I might see what sort of work I produced if I let my imagination go freely," Allan replied, somewhat less self-assured than he had been the previous night. "What in G-d's name could have possessed you to do such a thing," cried Arthur, nearly raising his voice. "After all I said the day before, why have you abandoned centuries of literary progress for some self-indulgent fantasy?" He shook the papers at Allan, raising them like a belt above the head of a disobedient son. "This is nothing but a glorified Grimm's tale, a miscarried child of Stoker, a creation less fit to be published than to be told around an open fire at the hovel of some peasant!" He spoke the last word with such heavy intonation that Allan shrank back before the physical wave of sound emanating from Arthur's throat. "Do you hate the modern system of literature? Do you personally despise the works the Enlightenment or the progress made since Shakespeare?" For a moment, Allan could hardly do more than shake his head. "No, of course not I " "Then why," Arthur barreled on, "do you disregard them all and return to this superstitious babble, this morbid, paganistic drivel?

What did Arthur ask Allan?

Sometimes a full Moon moves through Earths shadow. This is a lunar eclipse . During a total lunar eclipse, the Moon travels completely in Earths umbra. During a partial lunar eclipse, only a portion of the Moon enters Earths umbra. When the Moon passes through Earths penumbra, it is a penumbral eclipse. Since Earths shadow is large, a lunar eclipse lasts for hours. Anyone with a view of the Moon can see a lunar eclipse. So unlike a solar eclipse, it doesnt get dark on Earth. Instead it gets dark on the Moon. Partial lunar eclipses occur at least twice a year, but total lunar eclipses are less common. The Moon glows with a dull red coloring during a total lunar eclipse.
How is a lunar eclipse different from a solar eclipse?
