Device Ignitor Boulder is a bouldering area on State Trust Lands Tonaquint Block in Utah, managed by the State Land Board. It sits among a cluster of other climbing spots, with Tee Pee Boulder, Ripple and the South-West End/Pink Lady Area each about 0.1 mile away. The area is a bouldering hub, with seven routes all rated on the V scale. They range from the easy V0 of Bunsen Burner and Spark Plug to the V6 of Device Igniter Left. Device Ignitor Middle and Device Ignitor Right fall in between at V5 and V3. The climbing is all bouldering, so there is no rope or anchor to set up before you start. Spring and fall are the most comfortable times to visit. Typical averages from the nearby St George weather station put April highs around 75°F and October highs around 79°F, while July averages climb to about 102°F. The Zen Trail mountain bike route is about half a mile away, and Siler Loop and Bupstarch Loop are both under a mile off for hikers.
