Please edit these maps:
To edit them, you'll need a google account and maybe Firefox or Internet Explorer (I'm not sure about Safari). Your edits may not show up in the Map Channels map immediately. If you do a lot of work, you can make a copy of the map to save your work--ask me how (and I'll make a copy too).
If you'd like to work on importing the data from Community Farms and Gardens, let me know--I have some ideas.
To work on the canyons, visit Sierra Club Canyons Campaign. Eric Bowlby may have some GIS data that could be imported.
There may already be data in google earth about these sites, but my computer is too slow to check. Let me know if you take the time to search around in google earth.
