D1266A is a 1.75-mile straight-through connecting trail between Spring Canyon Bottom and Tibbetts Arch that follows a rusty pipeline its entire length. The trail is part of the Hell Roaring Rim Jeep Safari route and is most commonly run from north to south. The trail surface is a mix of sand and slickrock, with one long sandhill climb approximately halfway through and scattered slickrock ledges 8"-12" tall. The sandhill is deep, soft sand and offers a complete bypass route. However, any high clearance 4-wheel drive vehicle should easily conquer the hill with a little momentum. There is no suitable camping along this trail, but several wide areas of trail where you can pull over and enjoy the views.
