The Lousy Tank Ruin is located in the Agua Fria National Monument near Black Canyon City, Arizona. The pueblo style ruin looks like it has between 20-30 rooms. To get there, take I-17 Exit 259, follow the Bloody Basin Road for 10.9 miles, and turn right onto FR 14. Continue for another 4.8 miles and turn right. It looks like a person should be able to drive at least 2 miles before beginning the hike. That is how far the road goes on the map. From there it would be another 3.5 miles to the ruin. All but a half mile of that might be a faint 4WD road. Of course, if they happen to be reclaiming the road then all of it would have to be hiked.
Included with this post is the GPS file and map that we plan to use for our first visit. If you don't want to wait for us to get around to it feel free to try the GPS file and map for yourself. With no guarantee, of course, but they most often prove valuable for us.
