There is a
Cenotaph for Jeremy Glick located on a hilltop in Southern
California just north of
San Diego. It was created by a
geocacher by the name of
Mark71mark and more detailed information for finding this location as well as pictures can be found at this link...

The Cenotaph is a pile of Rocks about three feet high with a circumfrence at the bottom of around 30 feet with a Brass Plate naming Jeremy and the passengers of United Airlines Flight 93.
It is a half-hour walk from the nearest parking up a dirt road. The dirt road goes over the undeveloped hill so you can park at either end.
