I met up with my buddy Ben Baumann, a rare time our schedules and locations synced, to tackle Signal Peak, AZ (DPS #70), a P3K. It's in the Kofa National Wildlife Refuge, set up for bighorn sheep. The refuge's name (KOFA) was derived from an acronym for one of the area's notable mines, the King of Arizona gold mine. The trail followed Indian Canyon for awhile, then up a ramp on the left side avoiding dry falls. It was steep and steady most of the way. The summit area was large and flat. The ammo box that held the register was under some rocks. The benchmark was stamped KOFA2. We hung out on top for a while, then took our time heading down. It's an easy hike with cool scenery. Interesting that saguaros thrive here but don't exist 50 miles west in Cali. Gain was 2100', 3.8 miles RT.
