There are quite a few points in the UDDF file which are certainly not obstacles (note the catch basin in the road)
The ridge leading up to threshold would mask most of these points as well.
Here is the line on Google Earth
Here is the house with topped trees (note ridges beyond, also note eye level altitude of 808 feet, about 20 feet off ground surface alt.) This seems pretty close to where the aircraft was, and perhaps what they saw.
Ridge before threshold (note runway beyond)
