Английская Википедия:Bear Brook (Roaring Brook tributary)
Шаблон:Infobox river Bear Brook (also known as Bear Brook Creek[1]) is a tributary of Roaring Brook in Lackawanna County, Pennsylvania, in the United States. It is approximately Шаблон:Convert long and flows through Madison Township and Moscow.[2] The watershed of the stream has an area of Шаблон:Convert. Wild trout naturally reproduce within it. The surficial geology in the vicinity of the stream's lower reaches consists of Wisconsinan Till, Wisconsinan Ice-Contact Stratified Drift, bedrock, and alluvium. A bridge carrying Pennsylvania Route 690 crosses the stream.
Course
Bear Brook begins on a hill in Madison Township. It flows northwest for several tenths of a mile, flowing down the hill and entering a lake. From the western end of the lake, the stream flows west-southwest for more than a mile in a valley alongside Pennsylvania Route 690. It eventually passes a few ponds or lakes and turns west for several tenths of a mile, entering Moscow. The stream then turns south for a few hundred feet before turning west for a short distance, crossing Pennsylvania Route 690 and reaching its confluence with Roaring Brook.[2]
Bear Brook joins Roaring Brook Шаблон:Convert upstream of its mouth.[3]
Geography and geology
The elevation near the mouth of Bear Brook is Шаблон:Convert above sea level.[4] The elevation of the stream's source is between Шаблон:Convert above sea level.[2]
The surficial geology in the vicinity of Bear Brook in its lower reaches mainly consists of Wisconsinan Ice-Contact Stratified Drift, Wisconsinan Till, and bedrock consisting of conglomeratic sandstone, sandstone, and shale. However, there are also a few patches of alluvium.[5]
Watershed
The watershed of Bear Brook has an area of Шаблон:Convert.[3] The mouth of the stream is in the United States Geological Survey quadrangle of Moscow. However, its source is in the quadrangle of Sterling.[4]
History
Bear Brook was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1168851.[4]
In the early 1900s, the Lackawanna County Commissioners received permission to construct a bridge over the creek on Nork Road.[1] A concrete slab bridge carrying Pennsylvania Route 690 was constructed across Bear Brook in 1933. This bridge is Шаблон:Convert long and is situated in Moscow.[6]
In the early 2000s, the Lackawanna River Watershed Conservation Plan recommended that Madison Township include protection of Langan Creek in its zoning plans.[7]
Biology
Wild trout naturally reproduce in Bear Brook from its upper reaches downstream to its mouth.[8]
