(After several recent trail projects, I have decided to start documenting them on my hiking blog, to help my poor brain remember what I worked on.)
The New Mexico Volunteers for the Outdoors (NMVFO), joined by the Mule Deer Foundation, assisted staff from the vast 230,000 acre Sevilleta Wildlife Refuge to build a wildlife drinker on May 7, 2016 near the Pino Mountains along the western boundary of the wilderness.
About 18 volunteers mixed concrete in wheelbarrows and spread 3 inches thick on a plastic pond barrier, then inset flat natural rocks in the concrete, and finished the rim by stacking more loose flat rocks around the edge.
