Dale-

Some partial help here...you are exactly on the crux of why 'common names' 
aren't reliable.  Regional variations in 'local nomenclature' are remarkably 
intransient...even in today's age of multi-threaded communications systems.

 

I'll not weigh in on Penn. woods, as I'm not knowledgeable there.  

 

But I can tell you that much of the West (west of Rockies) refers to Pinus 
ponderosa as a yellow pine, particularly in its mature phase. Its bark retains 
a darker pigmentation until age and size causes the bark to 'plate out', 
exposing large yellow to gold (and with hybridization with Jeffrey pine) to 
red-brown platy bark, and darker furrows...these plates can be a foot across 
and 2-3 foot tall on larger trees.  And per recent posts, they have a very 
pleasant aroma when sniffed up close.

 

Do you have pictures?

Subject: [ENTS] "yellow" pine

ENTS,
 
I often have folks ask about "yellow" pine at Cook Forest.  I'm not entirely 
sure what exact species they're talking about.  They often think that "yellow" 
pine is it's own species.  A quick search of the term on the internet suggests 
the term "yellow" pine is often made towards a group of pine in the genus 
Pinus, but doesn't give an official name, kind of like calling any pine found, 
"yellow" pine.  
 
I'm thinking that they're most likely either talking about the park's pitch 
pine, or possibly more likely... a fond nickname for the ancient large old 
growth pine found here.
 
Can anyone clear this up for me?  These folks even go far back as claiming it 
as an old forestry term used to describe pine, but they still can't distinguish 
an actual species.
 
Thanks,
 
Dale
