it was a day where he joined the Interstate 10 and travelled east across the Arizona/New Mexico border to his 'significant' overnight stop between Lordsburg and Deming.
Approaching the New Mexico border along the Interstate 10, the importance of desert rivers for irrigation and farming is again clearly visible. The river here is a small tributary of the Gila River (described in yesterday's posting) and it eventually joins the Gila downriver of the Coolidge dam (again referred to in yesterday's posting). San Simon is the last settlement in Arizona on the Interstate 10 before the border with New Mexico and is located in this valley. Some photographs and a little of its history can be seen here . This source includes reference to the fact that cotton used to be grown on quite a large scale around San Simon supplying a local cotton mill and providing local employment. Low cotton prices in the late 1990s forced a reduction in cotton acreage and as a result, the cotton gin closed.
Beyond San Simon the Interstate 10 rises to a plateau andthe New Mexico border . Approaching the border Mark would have seen the sign of welcome below ('borrowed' from the Panoramio layer in Google Earth)
