Yes, I've traveled the area several times and camped in the NF between I-19 and the Tohono O'Odom. As you can see from the map I posted there is no physical connection between the San Xavier res and the Tohono O'Odom which is called the Papago res on the map although the P is cut off.

This camp they're talking about is a couple of miles north of the San Xavier res at the intersection of I-19 and Valencia.

Actually, map must be old. Papago is old name of tribe now called Tohono O. Every thing by San Xavier to Sells and south across Mexican Border is same reservstion of Tohonos. Tribe goes all the way down to Obregon, Sonora.
