The May 1968 issue of New Mexico Magazine has a good story and pictures on an annual jeep trip by the Las Cruces Four Wheelers and the Las Cruces Jeep Club. Fifty-five people in 17 four wheel drive vehicles, including at least one Landrover, Scout, Bronco, Flatfender and CJ-5 (several of these), made the 32 mile trip through a portion of the San Francisco River.
The article includes a map, pictures, and tales of their exploits. As you can see from the pictures, they spent plenty of time deep in water, crossing the river back and forth. The article begins on the map page (page 2). It’s a pretty large picture.
