Hiked from Hidden Valley Regional Park trough the canyon. Very scenic hike on a beautiful blue sky day. Much of the canyon is gentile until the top 1/4 mile or so. Then a rather easy hike along the power line jeep trail to the top. There was a large swarm of ladybugs on the summit cairn and surrounding rocks - SO, since this rock doesn't have a name, I am claiming it as "Lady Bug Mountain".
It took me about 50 minutes to reach the summit on Christmas Eve. Actually, I reached the summit at 3:59pm. There were several wild horses I saw on the way, including one horse that was a bit concerned since she had her baby horse with her.
