Several medium to tall spires and strange formations that when viewed from a distance look like one large jumble of stone. There are zero crowds, shade and sun depending on the route(s) and opportunities for other climbs if one enjoys loose and strange climbing. The rock quality is not great or even good but climbable and moveable (loose). Wear a helmet and choose a belay stance that is out of the falling rock zone.
Hike on the Dutchman's Trail toward Miners Needle, you'll pass a four way intersection, take the right route that leads in front of Sisyphus. When you feel it is appropriate step off the trail and hike to the formations. It takes around 1.25 hours from the Peralta parking area (4ish miles). The Sisyphus spire is the tallest formation but tends to blend into the area until one is closer to the base. It is the farthest set back as well. Casper looks like it sounds (the ghost) and sits alone, downhill from Sisyphus and closest to the trail you leave of to the right. The middle tower is Syphilis. Hard to see as two sub peaks block it until you are getting up it.
