Lone Star Boulder is a climbing area on county land within the Carter Lake unit in Colorado, about 7 miles from the town of Carter Lake. It sits among a cluster of other climbing spots, so it works well as one stop in a day of bouldering in the area. The most comfortable months for a visit are typically late spring and early fall. Typical averages from a nearby weather station at Waterdale, which sits a few hundred feet lower than the boulder, run to highs around 68°F in May and 76°F in September, with July the warmest month at about 87°F. Pocket Wall, Carter Lake and Extension Boulder all lie about 0.1 mile away. For a change of pace, the Sundance Trail is about 2 miles off.
