OverviewDisclaimer: I personally have not done this route in entirety. However, I have been up Jett Canyon to the point where one must leave the trail and ascend the ridge. My knowledge of the route comes 2nd-hand from Nick N, and the GPS track from his trip. Nick found the route to be scenic and pleasant.
This is a very long route, especially if you aren't willing to scratch up the paint on your 4WD. If you park at the last open area on the 2WD road, the hike is 19 miles RT, over 6000'. If you drive a farther 2.4 miles (4WD, high-clearance) to the (fallen) National Forest sign, your RT trip will be about 14.2 miles with 5300' elevation gain -- but your 4WD will have taken a lot of hits from tough branches.
WARNING: the USGS maps show the road continuing all the way up Jett Canyon to the high pass; this route is described in Hart's Great Basin Book. In actuality, the road stops at the point indicated in the map below; past that point, the road is so terribly overgrown with willow copses, that you MUST travel north onto the ridge as indicated, unless your skin is completely numb and like that of a rhinoceros.
Getting ThereFrom Las Vegas, take us 95 to Tonapah. At Tonapah, take US route 6 for 5.4 miles east to the intersection with state route 376. Take sr 376 an additional 47.1 miles north to the signed turnoff (left) for Jett Canyon (blue route on accompanying map). This signed Road is opposite Smoky Valley Road. This intersection is JETT376TRN in the waypoint list below.
Take Jett Canyon Road 4.85 miles WNW to the mouth of the canyon. This is about as far a 2WD, medium-clearance car will go. It is possible to drive 4WD, high-clearance vehicles another 2.4 miles to the Forest Service boundary, after which a berm is supposed to impede travel. This 2.4 mile section has much low brush that overhangs the road, and as of Aug 2006, was not suitable for any vehicle whose paint job was valued. ATVers, who apparently like Bud Light, may drive an additional 2.5 miles up the canyon, past the Forest Service boundary. Without an ATV, you must walk this next section.
The following account assumes you park at the end of the 2WD road.
Route DescriptionFrom the end of the 2WD-navigable road (JETT-PARK1 in the waypoint list), follow the Jett Canyon road for ~4.8 miles, till the road is on the north side of the stream at ~7900' elevation (JET-XC-START in the waypoint list below). Before this point, there are many stream crossings. In 2002-2003 the stream was principally dry in late summer; in 2006, it was flowing well.
The next part of the hike is trailless, and is ~4.5 miles long (in addition to the 4.8 miles you just walked).
Leave the road, stay on the NE side of the stream, and begin to work NW then N up the ridge. You want to cross a wash to the N and get on the NEXT ridge to the N; so contour across the wash to the next ridge, as soon as convenient. Continue N on the 2nd ridge, then NNE, then N, then NW, eventually going over the 10522' point on topo map (Arc Dome 7.5' quad). Then continue N to the false peak marked 11144' on the topo, and cut ~ENE over another false summit, eventually gaining the true summit.
