Fortalice Boulder is a bouldering spot on Bureau of Land Management land in Colorado, part of the Grand Junction Field Office. It sits among a tight cluster of other boulders, so it works well as one stop in a longer session. Spring and fall are the most comfortable times to climb here. Typical averages from a nearby weather station show May highs around 74°F and October highs around 66°F, while July highs average about 93°F. Several other problems sit within about a tenth of a mile, including BOGO Block, Black Wave Boulder Area and Bastion Block. For a change of pace, the Tabeguache Trail is about 0.7 miles away.
