Here you come to an old worker village, which has been abandoned for a long time and you can see a small "brother" of the door to hell crater as well.
Here are some remains from past time. While looking for the cache you will be able to see some of them. Very close to the cache you find also an old car. But look at it on your own.
From the main road you pass a small gas crater on the way to the cache. The difference to the "big brother" is that the one here is bubbling.
The cache itself is a petling which you should easily find.
It would be great, if you could attach photos.
Have fun
