If you go to the County information on the PGC website - click on Blair county - you will see it along the left hand side. Unfortunately - the PGC hasn't actually loaded the map of the SGL on their site. When you click on the #198 - there is an error message. I emailed the PGC a few months ago and the response was that there are a few maps that need loaded and to keep checking back.
This link should take you to the spot I am talking about.
