T J Lake is a climbing area in the Mammoth Ranger District of Inyo National Forest in California, managed by the Forest Service. It sits among a cluster of climbing and riding spots, with Lake Boulder and T J Slabs both about 0.1 mile away and the Tj Lake Loop mountain biking route about 0.2 mile off. The climbing here is alpine, with four routes ranging from 5.8 to 5.12a. Izzers is the easiest at 5.8, and Anaerobia is the hardest at 5.12a. The area is best suited to climbers who enjoy alpine styles. Summer is the most comfortable time to visit. Typical averages from a nearby weather station at Mammoth Lakes show July highs around 78°F with lows near 49°F, while winter highs stay around 41°F. That station sits about 1,450 feet lower than the lake, so temperatures at the climbing area run cooler. Lake George Campground and Coldwater Campground are both within a mile, and the Barrett Lake to Lake Mary mountain biking route is about 0.6 mile away.
