The Chamber is a bouldering area in Blue Mounds State Park in southeastern Minnesota, managed by State Park and Recreation. It sits among a cluster of climbing areas, with The Metamorphic Rock, North Quarry Area and North Quarry Talus all about 0.1 mile away. The climbing here is all bouldering, with six routes spread across the V0 to V4 range on the V scale. Mosh Pit is the easiest at V0, and The Prow is the hardest at V4. The routes are short and suited to a day of cragging rather than a long outing. Summer is the most comfortable time to visit. Typical averages from a nearby weather station in Rock Rapids, Iowa, show July highs around 85°F with lows near 62°F, while January highs average about 25°F. The station sits a few hundred feet lower than the park, so temperatures on the rock may run slightly cooler.
