Slab & Wesson Boulder is a bouldering area in Washington's Mt. Baker-Snoqualmie National Forest, within the Snoqualmie Ranger District and the Middle Fork Snoqualmie Natural Resources Conservation Area. The land is managed by the State Department of Natural Resources, and the boulders sit among several other climbing spots, including the nearby Philosophical Sandeagle Boulder and the Highway Ditch Zone, both about 0.1 mile away. The climbing here is all bouldering, with five routes ranging from V0 to V5. The Slab & Wesson route is the easiest at V0, and the Slab & Wesson (Sit) is the hardest at V5. All the routes were first ascended by Daniel Montgomery and Trevor Taylor in 2021. Summer is the most comfortable time to visit. Typical averages from the Cedar Lake weather station, about 6 miles away, show July and August highs around 70°F with only eight or nine wet days a month, while winter brings highs near 39°F and regular snow days. The Climbing Access Loop Trail starts about 0.2 mile away, and the Neverland Climbing Area Trail is about 0.6 mile off. Tinkham Campground, roughly 3 miles away, and the Cedar River, about 5 miles away, are the closest places to camp and paddle.
