I’m accustomed to the good old square grid range, Township & Section legal land descriptions in Oklahoma. In Texas, I assume because it’s an older state with previous Spanish or Mexican customs in place, the land description system and geography of county roads seems somewhat random. How do you figure out things west of Boyd, Wise County, Texas about 5 miles? We owned about 20 acres west of Boyd but sold the surface long ago. We get a little bit of old oil and gas production from Devon (previously Mitchell Energy); lease names are: Harris, Petty, Horton, Wilson, Elam.
Texas is a hodgepodge of everything on legal surveying practices.
The GLO website has an interactive map that works well to locate block and section numbers.

I wrote an article on the home page with other Internet resources.
