Close to the historic Wall House and Tacony Creek. This hide replaces the defunct "E-Park 1 - kind of close to the Wall House" cache by chsmathcrazy.
See the Related Web Page link for information about the Richard Wall House Museum which is open for tours on Sundays from 1:00 PM to 4:00 PM. From parking, you will pass two information displays regarding the mill that used to be where you are walking.
The coords may be a bit "soft" due to nearby power lines.
NOTE: As dfl1 pointed out in his log, there appears to be a benchmark in the NW corner of the bridge within 15 feet of the cache.
