We updated our website & launched our nifty new interactive map in ArcGISonline. All three open segments on one map!
Free ArcGIS public accounts for laptops at argis.com
Explorer for ArcGIS by ESRI is free too, in Google Play and iTunes. No account is required to view maps. Your location will appear on the map. Quality is dependent on your browser and device.
Public safety advice: a device is not the only tool needed to safely travel on the MCCT. We recommend a paper map (pick up online or at a Stanislaus National Forest Ranger station), and/or a compass too.
