Very cool story, loved iti
I had one encounter with a creature that gave off the very same unconcerned, totally unafraid vibe as the wolves did- snorkeling in the caribbean ages ago, encountered a barracuda. The vibe was palpable through the 20' of water that separated us.
Yes Cory ungulates, rodents, I'm guessing they lived on that sort of thing.
As for the status of the terrain we were working for Israelis "making the desert bloom" it's not sand dunes type btw.
We had access to water so tomatoes, melons, dates, etc.
Here's a google earth picture from the nearby road. Plus one of an Arabian wolf, smaller than most other subspecies apparently.
