Upper Mighty Mouse Wall is a climbing area in Colorado on Bureau of Land Management land within the Grand Junction Field Office. It sits in a tight cluster of crags, so it pairs easily with neighboring walls in a single outing. Late spring and mid-fall are the most comfortable times to visit. Typical averages from a nearby weather station show May highs around 74°F with lows near 49°F, and October highs around 66°F with lows near 41°F. That station sits well below the wall, so temperatures up at the crag run cooler. Lower Mighty Mouse Wall and Space Balls Wall are each about 0.1 mile away, with Juniper Wall about 0.3 mile off and the Main Trail roughly 0.6 mile away for anyone wanting to add a hike.
