Several warnings before I get into this -
A majority of Storey County is PRIVATELY OWNED -- including a road I was originally recommending. If you begin this trek from Virginia Highlands, take Lousetown Road. It is by far the worst road, but it is county property.
Should someone come along and decide they just want to make your life hell, here are the two laws that will without a doubt be thrown at you. The Archeological Resource Protection Act (ARPA) of 1979 and the Nevada Revised Statutes (NRS), Sections 381.195 through 381.227.
I will state the obvious, sign or no sign, this location is protected by state and federal laws.
Personally, this is such a remote location, and a majority of geocachers are responsible people, I see no reason why such a fragile and sacred site should be locked behind the shroud of secrecy. The more people who know and respect this site, the larger a force there is to stand up and protect it against those who have no respect and intentionally or not, destroy this precious location.
Going with that, I HIGHLY encourage you to follow the following:
Take Nothing But Pictures, Leave Nothing But Footprints, Kill Nothing But Time
This trek definitely falls under the journey is more important than the destination, though the destination makes the journey worth every jaw-jarring rock. Lousetown Road is the way to get here from Virginia City, those following the Virginia Range Trek #1 will find another access point. You'll be traveling through the Virginia Range, loaded with history extending back tens of thousands of years. From the V&T toll roads, to Comstock miners and ranchers, to ancient Native American sites, the whole area is astounding.
A high-clearance 4x4 is required as well as a full supply of desert off-road gear. Water being the highest on that list, especially during the summer months. Also, the road does cross at least one stream, not deep, but still has a rocky bottom.
The cache is located at the mouth of an impressive site. There is parking east of the cache - DO NOT DRIVE BEYOND THE FENCE - and if you continue along the road, you will see what all the pictures only hint at. There are an estimated 2,000 individual panels contained within a mere 1/4 mile. I recommend taking the day and going out here to have time to take it all in. Definitely worth the effort. Also, this whole area is prime mustang grounds, so do not be surprised if you see a herd or ten.
The road is slow going, and it'll take approximately one hour to reach the site. During the summer, the basalt boulders become extremely hot, and also provide much needed shelter for a nest of rattlesnakes. Use caution and maintain a sharp eye on any little ones who come along with you.
Please enjoy this site, and do your part in protecting it by not touching the art (oils react the the varnish), not removing anything from the site, not damaging the rocks (boot scuff marks, graffiti), and working to educate others about the delicate nature of these locations.
I love geocaching because it takes me places I would never have seen without it. I would not want to see geocaching become the reason these places are shut down.
