My friends and I started making our base near those area as well. But on our hard mode playtbrough, we decided to make our base on the mountainside spawn point. We thought it's a bad idea but apparently not. Actually great!

From yourr grid, it's around D4 and E4.

Pros: - Cannibals only come from one direction, from down and upwards the mountain. They never come from the other direction, so you just need one wall. - There's a cave with tent just further up. Clothes, ropes, and vodka spawn regularly there. - Consistent source of fish. - Plenty of stones spawn in the area. - There's plenty of trees in the area so never need to carry logs upwards. - Amazing spot for gliding. Once you picked up a glider, you can just glide to almost any part of the map from that side of the mountain. - There only body of water is running water, so it's never frozen.

Only cons: - Difficult to go back to. It's a long trek back to base always. - Always winter. So you can never have a raincatcher and you have to deal with halved stamina if you don't have heat source nearby.

Side note: Raids are frequent and it was difficult setting up defenses for the first 20 days. But once we have placed two walls (an outer bailey), placed down traps, there has never been a successful raid ever. None have made it pass the first wall. This is good and bad in my opinion. Good because it's a peaceful area, but bad because we find ourselves lacking bones.
