**A PROBLEM is a term used in bouldering. It is the path that a climber takes in order to complete the climb. Same as a route in roped climbing. Having holds already carved into the surface is just one benefit of an Eldorado Boulder.

Custom Boulders

Our artists can bring your vision to life. These boulders look and climb like real rock.

We specialize in matching rock whether it's in your backyard or an iconic destination - a rock at the base of El Capitan in Yosemite, a sandstone cliff in the Utah desert, or the volcanic rock of Devil’s Tower.
