While browsing through the Anthropology stacks at UNM's Zimmerman Library I came across this fine little guide by Dennis Slifer which describes eight publicly-accessible rock art sites along the upper Rio Grande. Slifer has packed a large amount of up-to-date information into this small pamphlet about the locations, dating and interpretation of New Mexico rock art.
The last site described in the guide is Tomé Hill south of Los Lunas which is about a half hour drive south of Albuquerque. I had never visited the site before, so the next morning we drove there, following Highway 47 south.
We only had about an hour available to explore the site, but that was enough for a first visit as the rock art is plentiful and easy to get to from the parking lot south of the Hill. I have put together a new page about the Tomé Hill petroglyphs at my New Mexico Rock Art web site.
