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.
