Anomalies are little stone cairns that can be tuned with your radio, unlocking an audio. Your dial indicator will turn red when you are near one.

You can start to collect these as soon as you visit Harden Tower for the first time, but two of them require que WAL Radio, that you'll unlock during the story. Unlike the letters, there's not always an anomaly on every zone, and some of them will have two. So this is the list of the 12 anomalies:

NOTE: If the achievement doesn't unlock when it should, try this suggestion from Holzi91: "Hey, I justed wanted to add: sometimes this achievement does not unlock, when you find the last anomaly. In that case quit the game and start it again. The achievement should unlock during the start".

There are a total of 12 anomalies available in the game, and they appear as a small formation of rocks that can be tuned into using the radio. Some of them are found behind locked doors, so it is advised that you wait until you unlock the new radio before going for all the collectibles. While going for anomalies, you should also go for Maggie Adler's Letters in order to unlock:
