Earlier I posted that I think Philip's body was found near where the water tank r and t letters were on this map
https://www.ebparks.org/civicax/filebank/blobdload.aspx?BlobID=29796 (zoom into 200 percent). Now that the SF Chron posted a more detailed map, it could be where the dashed red lines meet instead, a little to the right of the r and t letters.
The North Ridge trail from where Philip was running goes north goes to the top of the hill where he was found and the trail simply stops (see Google maps satellite view). From the map above in the first paragraph it looks like a fence blocks a trail toward the north where he may have been able to get out. It is possible that Philip got to where the North Ridge trail ended and simply was trapped and could not find a way out. If that fence on the map is accurate, maybe that fence blocked his way out of the park.
When I look at the hill where he was found, I even think I see a lot of black poles that mark the fence shown on the map in the Google aerial photo---https://
www.google.com/maps/@37.6876952,-121.9542778,62m/data=!3m1!1e3 You have to look carefully to see the series of black poles. The black poles extend in both directions when I scroll back and forth. It is possible seeing that fence that he was literally trapped on that hill with no way out.
So what is the fence? Well, I looked at the parcel viewer on the Alameda County website. The address is actually split into two parcels that EBRPD purchased from the Pooles in the 1990s. One is APN 941-2600-2-9. The other is APN 941-2600-3-3. One theory I have is that the fence divides the two parcels. I am hoping this is not the case, but I am troubled with the idea that Philip possibly could not get down off of that hill because of this fence which may have blocked him from getting out of the park. You can see the details on the Parcel Viewer if you search the Alameda County Parcel Viewer. The photos show the red boxes separating the parcels. It won't let me link to the looked up data but you have to search the address itself to find the information here
Geocortex Viewer for HTML5 To me it looks like the fence runs east to west and is along the border separating those two parcels.
If the fence was not there, the path it blocked led to the driveway that exits at Dublin Canyon Rd here
Google Maps
The house on the property at 11025 Dublin Canyon Rd where the EBRPD maintenance supervisor resides is downhill and shrouded by trees when I search that address on Google Earth. Philip may not have been able to see the house from the top of the hill, may have gone to the house and possibly no one was there, or perhaps the gates (I see 3 dots indicating gates) around the house prohibited him from getting to it. It is difficult to say what happened.
I hope the watch data may be able to provide details as to what happened.
