After our morning adventures on the east side of Route 85, when we found our first US-Mexican boundary monument and hiked to the triangulation station SHACK, we decided to follow up with more survey mark hunting on the west side, along Puerto Blanco Drive. I was hoping to complete the series of benchmarks all along Puerto Blanco Drive that we began two years ago. That was the day of Rich's scorpion sting, and I hadn't had much time to look up the data; we were basically just hunting for a few of the marks based on estimates from the topo map, and monuments/witness posts that we could see from the road.

This time, we were hoping to find the others. We did quite well, finding all but two. E 308 was our first along this road for today, and it was an easy find. The monument was easy to spot, and the disk is in good condition. The witness post is gone, but its concrete base is still evident at the site.
