Falling Ant Slab is a bouldering area in Grand Teton National Park in Wyoming, managed by the National Park Service. It sits among several other climbing spots, with Shoreline Boulders and Cutfinger Rock each about 0.1 mile away, and Red Cross Rock at a similar distance. The area is a cluster of boulder problems rather than a single route, and all eight of its listed routes are boulders. The climbing here is low-grade, with most problems sitting in the V0 to V2 range. North Slab Center is a V0, North Slab Traverse is a V1, and Southwest Traverse is the hardest at V2. The North Slab Left offers a V1-2 option. The boulders are close together, so it's easy to string several problems into a short session. Summer is the most comfortable time to visit. Typical averages from a nearby weather station at Moran show July highs around 77°F with lows near 42°F, while winter brings highs in the mid-20s and regular snow days from December through February. A fee is charged for park use. Aspen Knoll and Rock Beach are both about 0.2 mile away for a short hike. For an overnight stay, Toppings Spread 2a and Toppings Spread 4 are about 8.3 miles off.
