Rosetta Stone is a climbing area in the Mcdowell Sonoran Preserve in Arizona, on county land. It sits among a cluster of other climbing spots and trails, so it works well as a stop in a day of exploring the preserve's rock and hiking routes. Spring and fall are the most comfortable times to visit. Typical averages from the nearby Pinnacle Peak weather station show March highs around 72°F and November highs around 72°F, while July and August average in the upper 90s. Granite Ballroom is just 0.1 mile away, and Boulder Trail is 0.2 mile off. Sven Towers and Sven Slab are both within half a mile. For an overnight stay, Box Bar campground is about 8.5 miles away.
