Straight Run Loop
Distance: 14 Miles Topo/GPS Map
At the bottom of the hill you come to another T intersection. Turn left onto Sand Road. There is a road sign and a state forest bulletin board. Follow Sand Road for about 2.7 miles. The ride on Sand Road is very nice. It starts flat and then a nice downhill. There is a good view off to the right as you break out of the woods at the start of the downhill. Unfortunately, the downhill is followed by an uphill climb, which at this point in the ride is not welcome, but it's not very long. At the top the road flattens out and begins a long downhill drift. There are some wetlands and beaver ponds to the right of the road near the intersection with the Hesselgessel Road.
Continue straight until you come to the intersection with Right Asaph Run Road. This intersection can be a little confusing as it's in the form of a triangle. Sand Run Road splits into two prongs and Right Asaph Run Road forms the base of the triangle. Just keep to the left and you can't go wrong. Turn left onto Right Asaph Run Road. Right Asaph Run Road continues the downhill drift for another 3.4 miles. After 2.5 miles you come to the intersection with Left Asaph Run Road. Turn left at this intersection. There is a forestry department picnic area and campground at the junction of Right Asaph Run and Left Asaph Run. The area is very scenic, perhaps the most scenic woods in the county.
Follow Asaph Run Road downstream. About one mile below the picnic ground is a bridge across Asaph Run and a short uphill. After another .5 miles you exit the state forest and begin the last of the decent into Marsh Creek Valley. Continue straight through the small Village of Asaph. At the T intersection with Marsh Creek Road, turn left. After .5 miles you'll be back at the research lab.
