Set just off the roar of Interstate 80 in Wyoming lies Tree Rock, a solitary granite boulder that draws climbers seeking a unique offwidth experience close to the highway’s pulse. Unlike its namesake tree-bearing neighbor, this remarkable formation sits a few hundred yards east on the south side of the freeway—a granite slab cut by a perfect splitter offwidth that promises a rare and solid challenge for crack lovers. The stone here shares the same granite quality found throughout Vedauwoo, a nearby climbing hotspot, lending confidence to your gear placements and movement.

The approach to Tree Rock is refreshingly straightforward though requires a fence hop, a small rite of passage that climbers must navigate to reach this public land formation. Starting from Laramie, travelers driving west on I-80 should slow down around the "Tree Rock" exit and scan the left side before passing the official exit. After pulling well off the road, the fence is crossed carefully on foot to find the east face’s perfect offwidth crack. At 8,025 feet elevation, the area experiences Wyoming’s signature wind, but the boulder’s position largely shields the offwidth from gusts, allowing steady climbing conditions.

This slice of granite offers one classic climb that has secured its place in local legend: For the Commuter (5.9), a route rated 4.5 stars by climbers who appreciate its clean lines and reliable holds. It’s a climb that rewards precise technique more than brute strength, making it approachable yet satisfying for those who value quality over quantity. While the route count is modest—there may be a few additional lines to explore—it’s the purity and consistency of this offwidth that make Tree Rock a worthy stop.

Weather-wise, spring through fall offers the prime climbing window, with Wyoming’s dry air and clear skies prevailing in these months. The granite’s texture weathered by dry years provides excellent friction, crucial for keeping steady on the splitter. That said, bringing wind-resistant layers is advised, given the exposed location near the interstate.

Protection gear for this offwidth should emphasize solid placements in wide cracks; climbers should prepare for traditional pro setups since bolts are not indicated and the main ascent depends on jammed cams or big pieces. The approach’s terrain is flat and straightforward—no long hike, but the fence crossing calls for eyes on safety and respect for land boundaries.

Tree Rock’s proximity to Vedauwoo connects it to one of Wyoming’s best-loved climbing regions. Climbers visiting the area can consider this boulder a focused detour that offers a taste of the granite experience without a lengthy trek. The nearby classic climb, For the Commuter, is a neat, intense problem that challenges body positioning and patience on the offwidth, perfect for climbers keen on honing crack skills or enjoying a simpler yet rewarding outing.

Aside from the rock itself, this spot offers a subtle reminder that great climbing can exist quietly beside busy roads, offering a quick adventure and solid climbing close to civilization. Ideal for a half-day session or a repeat warm-up before dialing into more demanding climbs nearby, Tree Rock delivers a grounded adventure where skill and focus meet the rugged essence of Wyoming granite.
