Bouldering at Mosaic We strive to provide a wholly unique bouldering experience with high quality, though tful routesetting for climbers of all ability levels. Grading/Circuit System We use a circuit system to denote the approximate difficulty of each boulder problem in the gym. Each Circuit is comprised of roughly two V grades. Starting a Boulder Each boulder has a colored circuit tag placed next to the start hold(s). The color of the tag is the indicator for difficulty. Some boulders will have a single start hold with a single tag , while others will have two start holds clustered around a single tag. Sometimes, there will be two start holds placed farther apart. In this case, there will be an additional "no-color" tag placed next to the additional start hold. (The color of the holds does  not  correspond to the difficulty of the boulder.) Finishing a Boulder Boulders generally finish at the top of the wall unless otherwise indicated by a "top" tag.   SAFETY & ETIQUETTE Keep the pads clear.
