I was working as an assayer at the Sabina mine. While it wasn't isolated i the true sense, it was 2 hr ride through open country that hosted only a few ranchos. I would get off for a day or so every two wees. My wife and I used to go to the nearest town, Navajoa, Sonora, for supplies, course we always included hard candies for the isolated ranch kiddies, for their and their mothers, delight.
The summer moonsoons had arrived and it rained almost every day. So we had to plan our trips in between thnder storms.
There was one patch we calle the Llanreros, it was a wide velley with a central water course running through it, no problem except that it was pure adobe.
I don't know if you have ever experienced pure adobe that was wet. It is exactly like heavy grease. Off road tires are useless since it would quickly fill up any design in the tire, even the heavy knobbed ones promoted as off road . Loose Chains are the only way to go.
In effect you would end up with a smooth faced tire. You can imagine how difficult t would b to try to drive cross country in more wet Adobe - impossible, no traction or stearability.
Since a heavy storm had hit the area an hour or so before we arrived, it was impossible to proceed, so we decided to wait the night out and try to continue the next morning.
The pickup bed was loaded with suppplies, so we decided that my wife should try to sleep in the cabin alone, she could partially stretch out without me. She left the windows open since it was so hot and humid, while I proced to make myself comfortable

on the tail gate. Fortunately it was fairly level.
a few hours after darkness fell. I was awakened by a series of grunts, a pair of big cats talking back and forth. Knowing my wife could hear them also, I called out "listen to the farmers pigs. She remined silent. She told me the other day that she knew what they were that's my wifie.
At one time one or more were directly under the tail gate and I was getting nervous knowing that a big cat was noseing round only a few feet from me in the dark
This went on throughout the night, keeping me awake. ( and nervous )The next morning I found what the attraction was, it wasn't me, but a yearling that had drowned during one of the heavy runoffs just across the road, and the cats were feeding on it
If I had known I would have been extremely nervous, it doesn.t pay to get between Jaguar and her feeding sites, they get extremely nervous and aggressive
From the tracks we estimated that they must have been in the 350 lb class, a rareity in Sonora which generly run betwen 150 - 350 lbs. - I would be considered at disadvantage - no firearms or claws, let alone teeth.
