Accessed October 7, 2013.〕 Warren County is rolling hills, with the Kittatinny Ridge in the west. Allamuchy Mountain and Jenny Jump Mountain are part of the New York – New Jersey Highlands, also known as the Reading Prong. Around 450 million years ago, a chain of volcanic islands collided with proto North America. The chain of islands went over the North American plate, thus the Highlands were created from the island rock and so was the Great Appalachian Valley. The Highlands is Allamuchy Mountains and the Jenny Jump Mountains. Thus, Warren County was born. Around 400 million years ago a small continent that was long and thin collided with proto North America. This created the Kittatinny Mountains, as the land was compressed from the collision. The quartzite that was lying in a shallow sea over top of the Martinsburg shale, folded and faulted due to pressure and heat. The quartzite lifted, thus the Kittatinny Mountain was born. The final collision was when the African plate collided with the North American plate. This was the final episode of the building of the Appalachian Mountains. Then the African plate tore away from North America. Then the Wisconsin Glacier covered the northern part of the county from 21,000 to 13,000 BC. This glacier covered the top of Kittatinny Mountain and carved the terrain in the northern part of the county. The terminal moraine runs from north of Belvidere to south of Great Meadows to north of Hackettstown, to north of Budd Lake. Blairstown Township, Hope Township, half of Independence Township, part of White Township, and all of Allamuchy Township was covered by the Glacier. When the glacier melted, a lake was formed at Great Meadows. Slowly the lake drained leaving a large flat area filled with organic material. The county is drained by three rivers. All three rivers are shallow and narrow. They are fresh water rivers that are excellent for fishing. The Paulins Kill drains the western portion of the county. The river flows from Newton to Blairstown Township, and then through Knowlton Township where it drains into the Delaware River. The Pequest River drains the middle of the county flowing from Andover Township through Allamuchy, then to Independence Township where it turns west and flows through White Township and then empties into the Delaware River at Belvidere. The third river is the Musconetcong. Starting at Lake Musconetcong, the river divides the county from Morris and Hunterdon. This river drains the southern portion of the county and empties into the Delaware River near Warren Glen. Warren County is located in two valleys of the Great Appalachian Valley. The first is the Kittatinny Valley, which is in the northern part of the county, and the Lehigh Valley, which is in the southern part of the county. The Lehigh Valley starts at the terminal moraine of the Wisconsin Glacier slightly north of Belvidere. It extends from the Delaware River south to where the Musconetcong River goes into the Delaware River, northeast to the Jenny Jump Mountains and then along Route 80 to the Allamuchy Mountains to the terminal moraine near Hackettstown. The Kittatinny Valley is north of the terminal moraine; it runs north of Belvidere, to south of Great Meadows, then east to the north of Hackettstown. Towns such as Blairstown, Johnsonburg, Hope and Allamuchy are in the Kittatinny Valley The highest elevation is above sea level on the Kittatinny Ridge, at two areas just south of Upper Yards Creek Reservoir, west of Blairstown.〔(New Jersey County High Points ), Peakbagger.com. Accessed October 2, 2013.〕 The lowest point is the confluence of the Delaware and Musconetcong rivers at the county's southern tip, at of elevation. The highest elevation on Allamuchy Mountain is on the ridge northeast of Allamuchy. On Jenny Jump Mountain the highest point is east of the Shiloh area or south of Interstate 80. Sunfish Pond has an elevation of and upper Yards Creek Reservoir is at . 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Warren County, New Jersey」の詳細全文を読む スポンサード リンク
