This mountain is pretty hard to reach by any land route-- 15-20 miles makes a tough day, considering the paltry elevation (in fact, the peak is about 200' lower than my house in Vegas). But the trip is varied, scenic, challenging, and very hard to do in the short days of winter. I went when it was a bit too warm -- almost 80F at mid-day -- but I ran part of the way down sandy washes, and cached water along the way. There is virtually no way to reach the peak without gratuitous elevation gains and losses. This is a true test of desert rat planning and endurance. This peak was surveyed long ago, as it was originally slated to be one side of the Boulder Dam -- fortunately the location was changed, and the structure was eventually called Hoover Dam.
