Volunteers put in countless hours building Fox Hollow Nature Trail, a new two-mile path near Swope Park's Lakeside Nature Center. The loop cuts through riparian forest and limestone cliffs along Fox Hollow Creek. The foliage is so dense that hikers on a hot day will feel the temperature drop 10 degrees along the path, and the tree cover remains heavy throughout the journey. The manmade touches are nice, too: Eagle Scouts helped build a footbridge, and stumps form a stepladder over a fallen piece of timber. There are also escape routes at a couple of points for those who find their stamina lacking. Volunteers and former park official Ken Hightower spent three years building the path, and the work continues. "We still have another year or two before it's the premier trail in the entire metro, and that's what we're shooting for," says H. Gordon Havens, who proposed the trail.
