Do not be frightened by the name, this is not a scary night cache, just a challenging multi with a simple field puzzle so take your CRC book with you.
The first stage of this multicache is at the listed coordinates. The first stage information is easily seen at red-eye level from most places. I suggest looking back after passing GZ. I took the most reliable GZ, but it can move a little in these trees/rocks so do not be afraid to wander if necessary. No rock climbing! The final stage is on the ground and is the reason for the title. It is not required to scream at either location, but if you have emotions to let out, the scream will be your best available option.
Be cautious with your footing during your hike for this 5.0 Terrain cache. I would advise staying to the right instead of going up the middle. If you find yourself in fallen logs after the first 60 feet, you are too far left. You do not need to take special tools with you. No climbing is necessary.
