Spouse agreed to go on this one. It was billed as 7 miles long. We caught an Atomic City Transit bus at the Walkup Aquatic Center and were let off at the Camp Hamilton Trailhead below Eastgate, the industrial park on the main hill road. All these years I thought the pit dug in the tuff relatively near the trailhead was a game trap but it was actually for a pit toilet for the guard gate that used to be where the trailhead is now (and maybe also for the lab site that used to be there). Twenty people total.
Beautiful views to the east while going down the Camp Hamilton Trail but everyone was in such a hurry!! It was as fast as a Sierra Club hike.
After going down the Camp Hamilton Trail, we went cross country to the sewer treatment plant road to avoid San Ildefonso Pueblo land. Eventually we turned left onto the new Tent Rocks Trail that Craig Martin, Los Alamos county's open space coordinator, built with the help of volunteers.
It was very hot walking in mostly shadeless Pueblo Canyon. We sweated a whole lot. People finally asked to stop to allow a snack. It didn't look like a legitimate, leisurely lunch break to me so I waited to eat until after the hike.
Spouse did well but was tired by the time we got to the final uphill out of Acid Canyon on the Los Alamos Ranch School Trail. We got back before 1pm.
