Welcome, Margaret!! Yes, there is a small to medium sized herd of Elk in NW PA, in both Elk (appropriately named) & Clinton County, I am told. I am heading out to Elk County in two weeks with a friend of mine. We have been dealing with the Chamber of Commerce, who have been very helpful.
I was able to find this little article on their presence in PA. It is an old article (2000) and they were apparently reintroduced in 1999.
