About Bighorn Mating Grotto:

Cracks in a hard-to-find grotto tucked into the west side of Diarrhea Dome, that opens out toward the snowcaps of Big Bear.
Approach: From the Wonderland South day use parking lot just east of Barker Dam, hike north passing Uncle Willie's and the Astro Domes, at which point the trail will then branch off into two main washes, the left one leading northwest to the Lenticular Dome area and the right one continuing north and skirting in front of Freak Brothers Dome. Follow the wash on the right. Once past Freak Brothers, the tops of both Gumby and Diarrhea Domes can be seen. They look somewhat similar, but Diarrhea Dome is the one further back and has a pinnacle block that sticks straight up (Owl Pinnacle) in addition to blocks lying flat on top. On Diarrhea Dome, there are couple other gullys on the south side and southwest corner that lead up into the Bighorn Mating Grotto, but the easiest way up is on the west side, left of the gully with big chockstone blocks stacked near-vertical atop one another. There's a tree that grows inside this west gully, and the scramble up the slab left of this tree is less of a grunt fest than squeezing up the tight gully. Above, the U-shaped grotto faces west. Routes on the left side and middle gets afternoon sun, but Caught Inside on a Big Set on the right stays pretty much shady all day.
