Sad note: A recent check of Google shows that the dial was removed in early 2016 and the lot that supported garden education is now a housing complex.
In a small park at the intersection of Morningside Dr SE and Silver Ave SE in Alburquerque, NM. is a unique horizontal sundial designed for the Nob Hill Main Street program, where the 10-foot diameter sundial anchors the southeast corner of the Nob Hill Community Garden. Created several years ago by Mike Heighway and Mira Rose, Mike explains, "The purpose of the Nob Hill Sundial is to act as an interactive gardener’s guide. It works on an annual cycle by casting a shadow from a large center piece (the gnomon) onto a concrete plate with embedded steel [diurnal] bands and porcelain tiles that describe that month’s gardening activities."
The sundial acts as an educational tool for gardeners to show what to plant throughout the year, and when to harvest. Instructions are on porcelain tiles. There are a total of 17 tiles — one tile for each month of the year, one winter solstice tile, one summer solstice tile, one tile for both equinoxes, a centering tile (the tile which dictates the very center of the design), and a "hero" tile in the shape of a historic U.S. highway sign with information about contributors to the project. Most prominent is the acknowledgement of the Garden Design by Robert Strell and Grant Funding from the New Mexico Centennial Foundation.
