Carlton Boulder is a bouldering area in Temperance River State Park, within the Tofte Ranger District of Superior National Forest in northeastern Minnesota. The land is managed by State Park and Recreation, and the climbing sits just 0.1 mile from the Temperance River SP (North Shore) climbing area. The boulder field has seven routes, all rated on the V scale from V0 to V5. The easiest is Jacob's Ladder at V0, and the hardest is Gateway at V5. Finagle a Foot Slab and Phat Lip round out the lower and middle tiers. Climbers can pair a day on the boulders with the Summit View hike and the Sugarbush- Summit View cross-country ski route, both about 0.6 mile away. Summer is the most comfortable time to visit. Typical averages from a nearby weather station in Lutsen put July highs around 73°F with lows near 54°F. Winters are severe, with January highs averaging 17°F and lows around -3°F.
