Star Peak is also one of the sought after prominence peaks in Nevada as it ranks #6 on the list. While it is not one of the highest peaks in Nevada, it stands out rather dramatically from valleys around it, giving it 5400 feet of prominence.

If you don't understand what prominence is all about, here is a good explanation. Adam Helman recently authored a book completely dedicated to prominence.
The parallel (to I-80) service rd going back south from Exit 138 has been extended (there is much mining in the area). Further there are several roads going east off of the service road - it's easy to get a little lost in you haven't been there before. You want to go precisely 4.5 miles south from the freeway exit and take the road that goes east from there. It veers off to the left as the service road itself is making a left hand jog.
