Heberly Run

File:Waterfall on Heberly Run.jpgHeberly Run begins on the top of a mountain in Davidson Township. It flows east for a few tenths of a mile, quickly becoming highly steep. It then turns roughly south and its valley becomes very deep, reaching heights of approximately {{convert|500|ft|m}} within {{convert|2|mi|km}}. In this stretch, the stream receives Meeker Run, its first tributary. Eventually, Heberly Run turns southeast and then east, its valley becoming {{convert|700|ft|m}} deep. At the Lewis Falls, it receives Quinn Run and turns southeast. After approximately a mile, the stream's valley becomes {{convert|900|ft|m}} deep. Shortly after this, it enters the valley of East Branch Fishing Creek and reaches its confluence with that creek near the border between Sullivan County and Columbia County.

Heberly Run joins East Branch Fishing Creek {{convert|4.50|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|access-date = August 14, 2014|archive-date = September 17, 2015|archive-url = https://web.archive.org/web/20150917160158/http://www.lycoming.edu/cwi/pdfs/paGazetterOfStreams.pdf|url-status = dead}}

Tributaries of Heberly Run include Quinn Run and Meeker Run.

At its headwaters, the discharge of Heberly Run is 5,787,000 gallons per day. Downstream of the tributary Meeker Run, the stream's discharge is 12,931,000 gallons per day. At the mouth of Heberly Run, it increases to 24,076,000 gallons per day.{{Citation|author=Pennsylvania Department of Environmental Protection |url=http://www.dep.state.pa.us/dep/deputate/watermgt/wqp/wqstandards/TMDL/East%20Branch%20Fishing%20Creek%20TMDL%20Final%20110611.pdf |title=EAST BRANCH FISHING CREEK WATERSHED ATMOSPHERIC DEPOSITION TMDL Sullivan and Columbia Counties |date=December 2011 |access-date=August 14, 2014 |url-status=dead|archive-url=https://web.archive.org/web/20140903102046/http://www.dep.state.pa.us/dep/deputate/watermgt/wqp/wqstandards/TMDL/East%20Branch%20Fishing%20Creek%20TMDL%20Final%20110611.pdf |archive-date=September 3, 2014 }}

There are some ravines in the vicinity of Heberly Run.

Upstream of the waterfalls, there are smooth sandstone outcroppings in the streambed of Heberly Run. The stream has created a "steep and rugged" glen in the plateau that it is located on.{{Citation|author = Jeff Mitchell|publisher = Stackpole Books|url = https://books.google.com/books?id=1FqtMQ4Z2rsC&q=%22Heberly+Run%22&pg=PA114|title = Hiking the Endless Mountains: Exploring the Wilderness of Northeastern Pennsylvania|date = January 1, 2011|isbn = 9780811744232|access-date = August 18, 2014}}

There are a number of waterfalls on Heberly Run. These include Lewis Falls, Twin Falls, Big Falls and several others.{{Citation|author = Scott E.

Big Falls is {{convert|34|ft|m}} high and Lewis Falls is {{convert|22|ft|m}} high. The upper Twin Falls are {{convert|13|ft|m}} high and the lower Twin Falls are {{convert|9|ft|m}} high. There is also an unnamed waterfall that is {{convert|8|ft|m}} high. There are also waterfalls on the tributary Quinn Run.{{citation|author = Dan Styer|url = http://www.oberlin.edu/physics/dstyer/Backpacking/HeberlyRun2004.pdf|title = Hiking on Heberly Run, Pennsylvania|date = July 30, 2014}}

The vicinity of Heberly Run is described as "very scenic" in the Sullivan County Natural Areas Inventory.

The community of Jamison City is fairly near the watershed of Heberly Run.

There are second-growth woods in the watershed of Heberly Run. Trees found near the stream include hemlock and black birch. Other plants living there include wood sorrel and violets. A plant species that is threatened in Pennsylvania is found near the stream, as is one that is endangered in the state. The endangered species is becoming less common in the area.

The low pH of Heberly Run makes it difficult for fish to reproduce in the stream.

Heberly Run flows through the Pennsylvania State Game Lands Number 13. This area is less frequently visited than the nearby Ricketts Glen State Park.

A hiking trail known as Waterfall Wonderland follows Heberly Run for part of its length. A more difficult version of this hike is considerably closer to the stream and at times goes up the streambed itself. The trail requires bushwhacking in places.
