A new challenge has been launched. It focuses on city halls in California and Nevada. See the link below for details.
Please don’t forget that other US Topo map features can also be updated through the National Map Corps effort–schools, hospitals, cemeteries, and others. Please contact Carol or Drew if you have further questions. Have fun!
