Geography and geology
The elevation near the mouth of North Branch Bowman Creek is above sea level. The elevation of the creek's source is between above sea level. The surficial geology in the vicinity of the lower reaches of North Branch Bowman Creek consists of alluvial fan and alluvium. Further upstream, in the creek's valley, there is Boulder Colluvium, which is rich in boulders made of quartz, sandstone, or conglomerate. The valleys of North Branch Bowman Creek and South Branch Bowman Creek are the only places in the Sweet Valley quadrangle where this type of surficial geology occurs. Part of the creek's valley also has surficial geology of bedrock consisting of sandstone and shale, which occurs on the valley walls and part of the valley floor.
