This trip begins by turning off W-150 at mile #9 south of Evanston, between the two Sulphur Creek bridges. Here you turn northeast on the road going behind the Bear River City Historical Site. After two miles, you pass by a small road turning east around Oyster Ridge to Barrel Springs.
Stay on the main road to the northeast, up and over a divide, and after about three miles you begin traveling north along the base of Aspen Mountain. The road is closed at this point and no other 2017-Updates have been made for this trip! After passing Alamont, the road climbs up the side of the mountain above the railroad tunnel to a junction on top. Here a dead end road drops over the other side to Aspen (two miles) and the other end of the tunnel.
Stay on the main road going north along the top of the ridge. Up here you can see Medicine Peak to the northwest and Chapman Butte to the southeast. After three miles the road drops down the mountain and two miles further you come to a junction. Here you can turn northwest to another junction (two miles). There you can turn north one mile to I-80 (exit #18) and join W-189 going north to Kemmerer. Also at that junction, you can turn southwest and go past the Eagle Rock Ski Area to I-80 at exit #10.
Back at the junction at the base of the mountain, turn east and the road climbs a long hill. As you drop down the other side, you pass by an old building containing a huge boiler (the ridge off to the north is called The Boilers). Five miles further east, you cross Muddy Creek to a junction. Here you can turn northwest to I-80 at exit #24, or you can turn northeast to I-80 at exit #30. Also at this junction, you can turn south on the Piedmont Road and travel to either Mountain View or Evanston (see page 107).
