Poking around their site further, turns out they have a page called Earth Survey, a set of KML network links that installs those features into the stand-alone version of Google Earth, plus additional links that offer data not found in that web app. We could stop here, but let's place the map onto Google Earth.Two weeks ago, I posted about a web app from Metzger and Willard that offers useful info like PLSS data and a topo quad index in a Google Earth plugin interface. Mouse-over the purple dots to find sections 16 and 17.If you zoom in close enough, the sections are also displayed. The BLM townships are displayed on Google Earth.Under "BLM Townships, Ranges, and Sections", click the "View On Google Earth" button.To position the plat map, we also need section lines.T10S R2E is displayed on the Google Earth screen.Click the "Fly To On Google Earth" button.In the drop-down boxes, select "California", "Mount Diablo", "10S", and "2E". In the Google Earth "My Places" section, right click on "Earth Point Townships.

At this point, you could look for T10S R2E, but this is harder than it seems.Centered on T10S R2E, Santa Clara County.
