Remember the Historic Channels of Squirrel Hill map I made last summer? I've made a draft version of this map that is viewable on Google Maps!

(Be patient, it can be slow to load.)
The dark blue lines are existing watercourses, the light blue lines are historic watercourses I found on old maps, and the yellow lines are places where I think surface water once flowed, based on hydrology, but did not see on historic maps. The light red outline is the current Panther Hollow Run watershed and the maroon line is the part of the watershed that drains into the combined sewer-stormwater system. There are a few other features thrown in too. Click on the features on this map for more info.
Over time I hope to expand this map over the whole Four Mile Run watershed and add other features. Ultimately it will hopefully expand to be a big part of the outreach I am working on for my project.
I am currently looking at ways to get this on the version of Google Earth on 'smartphones', so that people can actually pull up this map while in the watershed and see where historic channels are. Stay tuned...
