Eventually comes the junction with Pink Hill Trail, which makes a short climb to another hilltop, with nice views over much of the forest and the Tucson suburbs beyond. From there, a few modest ups and steeper downs lead into a broad wash that is usually dry, and after crossing it, the trail gradually ascends to meet Squeeze Pen Trail. That trail traverses near the foot of Tanque Verde Ridge, over rockier terrain with elevated views. Try to notice how increasing elevation changes the species of cacti along the trail. Near the end of Squeeze Pen, an abrupt downhill through denser vegetation leads back to Loma Verde Trail and the first wash crossing, thus completing the loop.
