The hut at Gravel Bridge clearly wasn’t as secure as I had hoped. Zombies and skeletons invaded at night. I was forced to dig an emergency bunker, which is where I spent the night.
When day broke I continued following the waters north. I believe I have found the south eastern edge of the desert region, sighted on Day 15. I am currently digging a channel back to what I think are familiar waters.
On these channels I have established “Cactus Drift Station”.
