Yellow Fork is a great twisting singletrack through the oak trees. It is relatively low in technical difficulty and does not climb at to steep of a grade. It would make an excellent introductory ride on singletrack trails! It does get a bit narrow up at the top, which helps you learn to hold a line! About 1.5 miles into the ride you will make a very sharp right-hand hairpin turn around a fallen tree. The trail turns to a double track here. Stay right on the double track for .4 of a mile. You will see the singletrack continuing off to your right. Follow the narrow singletrack up the the scrub oak until you hit the doubletrack again. Look to your left, about 20 yards down the doubletrack, and you will see the singletrack again. From here to the top you will climb rather steep, narrow sections through the aspens! The trail turns north and breaks out into the open for a great view of the Wasatch Front and the Kennecott Copper Mine. From here on, we haven't had the time to explore...your on your own!!
