The watershed of the creek has an area of 4.33 sqmi. The creek has one named tributary, which is known as West Creek. The surficial geology in the vicinity of West Branch Little Muncy Creek includes alluvium, bedrock, fill, Wisconsinan and Reworked Illinoian Till, Wisconsinan Till, Wisconsinan Flow-Till, Wisconsinan Till Moraine, and Boulder Colluvium. The creek designated as a Coldwater Fishery and a Migratory Fishery and is being considered for addition to the wild trout waters list of the Pennsylvania Fish and Boat Commission.

Course
West Branch Little Muncy Creek begins on Huckleberry Mountain in Davidson Township, Sullivan County. It flows southwest for several tenths of a mile, entering Franklin Township, Lycoming County and crossing Pennsylvania Route 42 before turning south-southeast. The creek flows in this direction for several tenths of a mile along Pennsylvania Route 42, passing through a pond before turning southeast. After a few tenths of a mile, it turns south-southeast, entering Jordan Township and receiving its only named tributary, West Creek from the left. The creek then turns south-southwest for several tenths of a mile, still flowing alongside Pennsylvania Route 42. It then turns south-southeast for a few tenths of a mile before turning south-southwest. The creek then reaches the end of its valley and reaches its confluence with Little Muncy Creek.

West Branch Little Muncy Creek joins Little Muncy Creek 19.35 mi upstream of its mouth.

Geography and geology
The elevation near the mouth of West Branch Little Muncy Creek is 971 ft above sea level. The elevation of the creek's source is 1853 ft above sea level.

The surficial geology alongside West Branch Little Muncy Creek in its lower reaches mainly consists of alluvium. However, there is a patch of fill at the mouth and bedrock consisting of sandstone and shale occurs on the sides of the creek's valley. However, a large area of Wisconsinan and Reworked Illinoian Till occurs in the surficial geology further upstream, and there are a few patches of it near the creek's lower reaches as well. In areas with shale bedrock, this till's matrix is clayey silt, while in areas with sandstone bedrock, it is clayey sand. There are clasts of sandstone and conglomerate ranging in size from cobbles to boulders. Further upstream, there is Wisconsinan Till, Wisconsinan Flow-Till, and Wisconsinan Till Moraine. In the creek's upper reaches, on Huckleberry Mountain, the surficial geology consists of Boulder Colluvium (which is mostly covered in quartz, sandstone, or conglomerate boulders) and bedrock consisting of sandstone and shale.

The course of West Branch Little Muncy Creek passes through the furthest extent of the glaciers during the Wisconsinan Glaciation.

Watershed
The watershed of West Branch Little Muncy Creek has an area of 4.33 sqmi. The creek is entirely within the United States Geological Survey quadrangle of Sonestown.
