Mormon Mountains: Hackberry Springs is a 5 mile out and back trail located near Caliente, NV. The trail is rated as moderate and primarily used for hiking.
To find the access road to Hackberry Springs Road, go to mm 100 on I-15, 22 miles south of Mesquite, Nevada. Take the frontage road north. There is a BLM sign at the HB road left turn, but the sign is down. Go left to the trail head. The BLM informational sign says to follow the wash to the springs. Look for the petroglyphs on the left wall of the first narrow canyon. Follow the wash UNTIL IT GOES UP THE RIGHT CANYON. DON'T GO UP THE RIGHT CANYON! We did and lost 1 hour. Stay left and pick up the road that is due north right off the wash. We followed the road to the end after we returned from the detour, but never found the cement tanks. They were 30 feet up and to the right after we came to the end of the road. I don't know if they have water in them because we never found them. What we did see were the petroglyphs and three Bighorn Sheep: two rams and a doe. The hiking is difficult due to the "wash walking". This was not the prettiest hike, and not finding the cement tanks were frustrating.
