called the place he camped on the trail around the mesa next to the river as "El Contadero" (The Counting Place). It gave the mesa its name, "Mesa del Contadero," meaning the "Table of the Accountant," referring to the place along the mesa and the Rio Grande where provincial border officials counted the numbers of sheep being herded out of the province, south past them with the trade caravans into Mexico. This sheep trade had been the major item of trade for the province before the Revolt, and would be again after it recovered from the effects of the Revolt.

Also named on that map was the site of the Paraje de Contadero on the south side of “Mesa de Senecú” close to the Rio Grande. By the 19th century the ruins of Senecú had vanished, probably washed away in one of the large Rio Grande floods, and with it the Senecú name of the mesa, as memory of it faded.George D.
