Ashelman Run is a tributary of Coles Creek in Columbia County, Pennsylvania, in the United States. It is approximately {{convert|0.7|mi|km}} long and flows through Sugarloaf Township.{{Citation|author=United States Geological Survey |url=http://viewer.nationalmap.gov/viewer/ |title=The National Map Viewer |accessdate=December 22, 2014 |url-status=dead |archiveurl=https://web.archive.org/web/20120329155652/http://viewer.nationalmap.gov/viewer/ |archivedate=March 29, 2012 }} The stream's watershed has an area of {{convert|0.57|sqmi|km2}}. The stream is designated as a Coldwater Fishery. It is named after Daniel Ashelman, who lived in the area in the early 1800s. Glacial till and other geological features can be found in the vicinity of the stream. It has one unnamed tributary and there are two lakes in the watershed.
Course
Ashelman Run begins in a large pond in Sugarloaf Township, on the southern base of Central Mountain. It flows southwest for several hundred feet, crossing Pennsylvania Route 118. The stream then turns south-southeast. After a few tenths of a mile, it receives an unnamed tributary from the left. Some distance further downstream, the stream reaches its confluence with Coles Creek.
Ashelman Run joins Coles Creek {{convert|3.54|mi|km}} upstream of its mouth.{{Citation|url = http://www.lycoming.edu/cwi/pdfs/paGazetterOfStreams.pdf|title = Pennsylvania Gazetteer of Streams|date = November 2, 2001|page = 28|accessdate = December 22, 2014}}

Geography, geology, and watershed
The elevation near the mouth of Ashelman Run is {{convert|1033|ft|m}} above sea level.{{Citation|author = Geographic Names Information System|url = http://gnis.usgs.gov/apex/f?p=136:3:0::NO::P3_FID,P3_TITLE:1168447,Ashelman%20Run|archive-url = https://archive.today/20141223173407/http://gnis.usgs.gov/apex/f?p=136:3:0::NO::P3_FID,P3_TITLE:1168447,Ashelman+Run|url-status = dead|archive-date = December 23, 2014|title = Feature Detail Report for: Ashelman Run|accessdate = December 23, 2014}} The elevation of the stream's source is between {{convert|1160|and|1180|ft|m}} above sea level.
For most of its length, Ashelman Run flows over a glacial till known as the Wisconsinan Till. This glacial till is typically more than {{convert|6|ft|m}} thick. However, the stream's lower reaches are on alluvium containing stratified silt, sand, and gravel. The alluvium is approximately {{convert|6|ft|m}} thick. The stream also passes through a small patch of fill near its headwaters, where it crosses Pennsylvania Route 118. The Wisconsinan Till Moraine occurs a short distance north of its headwaters.{{Citation|author=Duane D.

The watershed of Ashelman Run has an area of {{convert|0.57|sqmi|km2}}. The stream is entirely in the United States Geological Survey quadrangle of Red Rock. It is located in northeastern Sugarloaf Township.{{Citation|author = Walter M. Brasch|title = Columbia County Place Names|pages = 6, 7|year = 1982}} There are two small lakes in the watershed of the stream. One is located in the watershed's middle reaches and one is located in its upper reaches.
History and etymology
Ashelman Run was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1168447.
Ashelman Run is named after Daniel Ashelman. Ashelman most likely moved from the Wyoming Flats to a location near the stream in the early 1800s. He also constructed a log cabin close to the stream. The land near it was still owned by the Ashelman family as late as 1982.
Biology
Wild trout naturally reproduce in Ashelman Run between its headwaters and its mouth.{{Citation|author=Columbia County Conservation District |url=http://www.columbiaccd.org/natural_trout_reproduction_july_2013.pdf |title=Pennsylvania Wild Trout Waters (Natural Reproduction) ‐ July 2013 Columbia County |page=1 |date=July 2013 |accessdate=December 23, 2014 |url-status=dead |archiveurl=https://web.archive.org/web/20140910195305/http://www.columbiaccd.org/natural_trout_reproduction_july_2013.pdf |archivedate=September 10, 2014 }} The stream is designated as a Coldwater Fishery.{{Citation|work=Pennsylvania Bulletin |url = http://www.pabulletin.com/secure/data/vol44/44-40/2066b.html|title = [44 Pa.B. 6235] [Saturday, October 4, 2014] [Continued from previous Web Page] FEDERAL WATER POLLUTION CONTROL ACT, SECTION 401|date = October 4, 2014|accessdate = December 23, 2014}}
