Steve, I'm 95% sure
this is the old Brickerville PA Youth Hostel. Almost everything is how I remember from 50 years ago (not 40 as I said in PM!), the open fields + the distance and proximity to town and Cannon Hill. The hostel is the building to the right, the houseparent's residence is the structure perpendicular to the left at a slightly higher elevation with a sloping terrace down to the hostel. I think most of Fox Road was dirt back then. The street view image of the driveway suggests that it has been since remodeled into more of a house.
I decided to post part of my PM just in case there are any other nostalgic hostelers in the audience!
