In the early days of aviation, navigation was always an issue. Old Plamosa Road leads to one of the innovative ways early airmail pilots found their way across the country. Rocks are laid out spelling QUARTZSITE with an arrow pointed roughly towards the town. Another arrow with a very large N points north. Low-flying aircraft navigated from sign to sign.
Old Plamosa Road is a bypassed dirt section of the original when the new road was paved. It is suitable for 2WD vehicles and crosses two minor sandy washes. The rock navigation arrows are fenced off from a large parking area. There are numerous campsites for rigs up to and including RVs.
North a short distance is the Bouse Fisherman, and intaglio rock art dating from at least a thousand years ago.
