Branching off D1290, D1291B is a sandy, rocky out-and-back trail heading just over a mile to South Fork Mineral Canyon. Although the canyon is less than grand, it still offers the beautiful desert scenery that this region of Utah is known for. A few small challenges await users, but nothing that a stock 4WD vehicle cannot handle. The trail used to continue further but is now closed where the .gpx track ends. No campsites along this route exist, but many nearby spurs offer great dispersed camping opportunities.
