Laurel Run is a
tributary of
West Branch Fishing Creek in
Sullivan County, Pennsylvania, in the United States. It is approximately long and flows through
Davidson Township.
The stream is in the United States Geological Survey quadrangle of Elk Grove. Wisconsinan Flow-Till, Boulder Colluvium, Wisconsinan Till Moraine, alluvium, and alluvial fan occur in the vicinity of the stream, as does bedrock consisting of sandstone and shale. The southern terminus of the late Wisconsinan glaciation is also in the area. A wood plank bridge on stone masonry abutment walls crosses the stream.
Course
Laurel Run begins in a valley in Davidson Township. It flows south for several hundred feet before turning southeast for a few tenths of a mile. The stream then turns south for a similar distance before turning southeast again and exiting the valley. It crosses Fishing Creek Road and a short distance later, reaches its confluence with West Branch Fishing Creek.
Laurel Run joins West Branch Fishing Creek upstream of its mouth.

A
glacial till known as the Wisconsinan Flow-Till occurs in the valley of Laurel Run.
This is the only place in the United States Geological Survey quadrangle of Elk Grove where that type of glacial till occurs.
It is a resedimented till that is texturally a
diamict. This glacial till occurs in the upper reaches of the bottom of the stream's valley. Boulder
Colluvium occurs in the lower reaches of the valley and contains
boulder
In geology, a boulder (or rarely bowlder) is a rock fragment with size greater than in diameter. Smaller pieces are called cobbles and pebbles. While a boulder may be small enough to move or roll manually, others are extremely massive.

Watershed
Laurel Run is entirely within the
United States Geological Survey quadrangle of Elk Grove.
There is a
bridge that crosses Laurel Run and the
Pennsylvania Game Commission has a permit to maintain it.
The bridge is a wood plank bridge on
abutment walls made of stone masonry. It has a span of and the opening that the stream passes through has an area of 65 square feet (6 square meters).
History
Laurel Run was entered into the
Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1209307.
