The road to the right leads toward Lecyr Well and Trio Mines, where I camped during my Mojave 2000 trip, while the left road leads to Keystone Canyon, and is my road today.
Back in 2000, I was also intending to enter Keystone Canyon, but I took the wrong branch of the road, partly because it wasn't on the map I was looking at and I had to guess (incorrectly) which fork to follow.
