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.

One look at Fred Rooney, and you just know he's the good guy. A trace of childish innocence in his face gives the lanky Bethlehem lawyer a Jimmy Stewart-like quality of quiet trust. In black jeans and button-down shirt, he's a kind of folk hero in the south Bethlehem melting pot where he's crafted a law practice catering to working-class families - mostly Latino - in the shadow of the hulkish remnants of Bethlehem Steel. A two-hour drive away, at City University of New York Law School in Queens, Rooney spends several days a week helping upstart lawyers develop storefront practices that, like his, provide legal representation to folks who can't afford a $250-an-hour legal counselor. Kristin Booth Glen, the law school's dean, took one look at Rooney and knew he was the right person to head the innovative Community Legal Resources Network. ''Fred's so low-key, he's Midwestern in effect,'' says Glen, a former New York Supreme Court judge. ''He captivates people, he inspires loyalty.'' For bringing legal representation to the poor and a host of other social causes, including finding medical care for seriously ill children in Latin America, the Moravian College Alumni Association has chosen Rooney for its prestigious Haupert Humanitarian Award. The award, given to only a select few alumni, will be presented at 7:30 tonight at a reception on Moravian's Priscilla Payne Hurd campus. Moravian, where he was an undergraduate in the early 1970s, inspired Rooney's deep sense of social justice. The son of a Bethlehem Steel executive in New York, he came to the Bethlehem campus from an affluent upbringing on Long Island. The young Rooney might have set his sights on Washington, D.C., like his uncle, former U.S. Rep. Fred Rooney of Bethlehem. After all, politics run in the Rooney family. His brother, state Rep. T.J. Rooney of Bethlehem, is a power in the state Legislature and the Democratic Party. But on a trip to Colombia when he was a junior at Moravian, the child of privilege saw human suffering, malnutrition and poverty the likes of which he had never imagined. ''I couldn't understand why we live this way and they live that way,'' Rooney recalled. ''It's been the guiding light of my life ever since.'' After graduating in CUNY Law School's first class in 1986, he took a job with Lehigh Valley Legal Services.

Animated history of the US. Of course the cartoon is highly oversimplified, and most critics consider it one of the weakest parts of the film. But it makes a valid claim which you ignore entirely: That the strategy to promote "gun rights" for white people and to outlaw gun possession by black people was a way to uphold racism without letting an openly terrorist organization like the KKK flourish. Did the 19th century NRA in the southern states promote gun rights for black people? I highly doubt it. But if they didn't, one of their functions was to continue the racism of the KKK. This is the key message of this part of the animation, which is again being ignored by its critics. Buell shooting in Flint. You write: "Fact: The little boy was the class thug, already suspended from school for stabbing another kid with a pencil, and had fought with Kayla the day before". This characterization of a six-year-old as a pencil-stabbing thug is exactly the kind of hysteria that Moore's film warns against. It is the typical right-wing reaction which looks for simple answers that do not contradict the Republican mindset. The kid was a little bastard, and the parents were involved in drugs -- case closed. But why do people deal with drugs? Because it's so much fun to do so? It is by now well documented that the CIA tolerated crack sales in US cities to fund the operation of South American "contras" It is equally well known that the so-called "war on drugs" begun under the Nixon administration is a failure which has cost hundreds of billions and made America the world leader in prison population (both in relative and absolute numbers).

Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen.
