Drove to the end of Jeroba Drive and started hiking on the jeep trail toward the peak. When the dirt road bent sharply to the left, I left the road and went x-country through the desert toward a gully. The HPS directions that I carried suggested aiming for the gully to find the desired route. Once at the gully, I found the rock piled gully route. Whenever I wondered if I was going in the wrong direction, I just looked for a man made rock duck further up. This worked well until I lost the rock ducks about 3/4 of the way up. I made my own route the rest of the way, which made the hike harder than necessary. I regained the established route before reaching the high point. The last yardage was a Class 2 or 3 boulder climb to the summit. I only stayed for a minute, since the sun was getting ready to dive behind the Desert Divide. Views from the top were peak filed in a 360 degree vantage point. Meanwhile, I followed the rock duck route back down the mountain, which was quicker and much easier to follow downward. I made it back to the car about 5 minutes before it got dark.
