From the Queen Canyon Mine entrance to the summit, via the Queen Canyon Mine route, it is approximately 4.5 miles; therefore, a round trip distance for the route would be in the neighborhood of about 9 miles. Knock off about 2 miles if you're able to drive all the way up to the saddle (would need a good 4-wheel drive vehicle).
Total elevation gain can be derived from the route description I provided..........................the summit is right at 13,140 feet; Queen Canyon Mine entrance is right at 9,200 feet. Therefore, the total elevation gain for the route is approximately 4,000 feet. Again, if you're able to drive all the way up to the saddle, knock off 500 feet of elevation gain (+/- 3,500 feet).
Hope this helps...............................happy climbing!
Note: There is another water tank on the left and dirt road on the right 6 miles from Benton. We drove in at night and upon seeing the tank just opposite of this road, we mistakenly turned off Hwy 6 too soon. There is a wire gate that does not state to Keep Out, as you might expect on a private road. Do not be confused by this road. Mark your odometer and be sure to take the correct road 9 miles from Benton, as stated in the route description. We took the wrong road for about 2 miles and were miffed at how rough it was. Queen Canyon Mine Road is quite gentle comparatively speaking.
My '92 Toyota 4-Runner made it to the 9700' saddle with ease 5/09/09. Full moon. Trail from there is great. Hiked by moonlight only, save < 2 minutes flashlight time. Rnd trip 6 hours. Minimal snow. No other idiots on trail. Dark.
