Drove a few miles down a rough dirt road to shorten the approach. Started at a point NE of the East Summit and followed the ridge up to the top. From there, we dropped down to the saddle and went up the steep face of Middle Summit before dropping down once again and making our way up to Dike Benchmark proper. It was mostly class 2 with minimal class 3 on the way up. Lots of loose rock. The summit boasts some amazing views and we were lucky enough to catch part of the air show at Nellis Air Force Base from the top of Dike Benchmark. There is also a collapsed structure and some canisters of acetylene at the summit. We tried to drop down the NE ridge of Dike Benchmark, but encountered some big cliffs. We changed course slightly and were able to find an easy break to descend. This would probably be a decent ascent route too, if you wanted to only do the main summit.
