There are two primary ways to use the maps: 

1. Select "present" on the left side and it will launch a tour of Union Vale, starting in Verbank.

2. You can zoom in/out of one or more sites (pins).  Red pins show sites that are no longer present and green pins show sites that still exist. 

Note that references are present in the pop-up windows and at the end of the "presentation" (tour).  

Viewers are invited to provide any additional information in an effort to continuously improve the maps. You can either comment on the Google Earth point, or you can contact us through the Contact Page.
