From Salt Lake head west on I-80 to State Road 36 which heads south towards Tooele. As you approach Tooele the highway will go up and over a bridge crossing the railroad tracks, take the first left after that bridge onto 1280 North. You will then take the next immediate left turn onto 2000 North which is also Pine Canyon Road. Take Pine Canyon Road to the small town of Lincoln and then make another left turn onto Churchwood Drive. The road to Pass Canyon is about 2000 feet north on Churchwood and heads directly east. Follow that road until you reach the BLM fence.
Pass Canyon, accessed from the tiny community of Pine Canyon (a.k.a. Lincoln) northeast of Tooele, had a jeep road that climbed up the canyon toward Barneys Peak. The road drops down into and traverses the head of Barneys Canyon on the SLC side and eventually ties into the access road leading to the communication facilities on Nelson Peak, the highest point in the northern Oquirrhs.
Pass Canyon (BLM land) is now closed to motorized vehicles, and is beginning to fade, particularly higher in the canyon. It is still open to mtn. bikes, and hiking. The route up Pass Canyon is not shown on USGS 1:24k maps (Bingham Canyon quadrangle), and despite being closed all of the roads are still visible in Google Earth if you click the roads layer.
No motorized vehicles are allowed on BLM land. The ridgeline of the Oquirrh Mountains is also the boundary of Rio Tinto/Kennecott property, with everything east of the ridge on the Salt Lake side being private property.
