Big Rock
About
Big Rock is a summit of 3,578 feet in the Iller Creek Conservation Area - Big Rock Addition in Washington, about 6.4 miles from Spokane Valley. Summer is the most comfortable time to visit. Typical averages from a nearby weather station show July highs around 87°F with only about four wet days, while winter highs stay near 38°F and lows drop to around 26°F. That station sits well below the summit, so temperatures up top run cooler. Climbers will find the West Face, Rocks of Sharon and East Face climbing areas all about 0.1 mile away. The Stevens Creek Trail is about 0.4 mile off.
