The first place to start when looking up land is checking with your county assessor site for all the information they can provide. In Mohave County you go to http://www.mohave.gov and click on assessor. Or click here.
Assessor Search | Mohave County
From here you type in the parcel number or an owner name to get more information about the land and property. Look for the GIS map link on the page and you will get an exact location of the property.
