At the East unit, the Tanke Verde trail climbs into the pine forests of the Catalina mountain.
Luckily, this one is harmless.
Balanced rocks near the Tanke Verde trail.Here at the trailhead, an effigy and a propped boulder stand on an outcrop, surrounded by prickly pear and ocotillo bushes. The effigy looks a little like a bird.
Now we can go the the west unit. The big attraction there is Signal Hill, a huge pile of boulders covered with geometric petroglyphs.
