Broad Hollow Run

Broad Hollow Run is a tributary of Bowman Creek in Wyoming County, Pennsylvania, in the United States. It is approximately 1.0 mi long and flows through Noxen Township. The watershed of the stream has an area of 1.04 sqmi. The surficial geology in the vicinity of the stream consists of alluvium, alluvial fan, and Wisconsinan Till. Its watershed is designated as a High-Quality Coldwater Fishery and a Migratory Fishery.

Course
Broad Hollow Run begins in a deep valley in Noxen Township. It flows north-northwest for several hundred feet before turning north-northeast and north for a few tenths of a mile. In this reach, the valley of the stream becomes much shallower on one side. The stream then turns north-northeast again. Several tenths of a mile further downstream, it enters the valley of Bowman Creek and reaches its confluence with Bowman Creek.

Broad Hollow Run joins Bowman Creek 17.70 mi upstream of its mouth.

Geography and geology
The elevation near the mouth of Broad Hollow Run is 1234 ft above sea level. The elevation near the source of Broad Hollow Run is between 1500 and 1520 ft above sea level.

The surficial geology near the mouth of Broad Hollow Run consists of alluvium (which contains stratified sand, silt, gravel, and some boulders) and a till known as Wisconsinan Till. Further upstream, the surficial geology consists of Wisconsinan Till and alluvial fan, some of which is underlain by glacial lake clays. The surficial geology at the headwaters consists entirely of Wisconsinan Till.

Broad Hollow Run is in the vicinity of the North Mountain region.

Hydrology and watershed
