Document #XXXX-II: Exploration II
D-7391 is a 36-year old Caucasian female of average build and appearance with no major medical history. D-7391 is equipped with a 30 liter backpack, knife, a sleeping bag, a compass, a tent for a single person, 500 milliliter bottle filled with 475 milliliters of water, an empty 250 milliliter water bottle, 25 nutrition bars, and a chest-mounted camera with live video feed with a microphone/speaker combination.
D-7391 is standing on the edge of a ladder leaning on the side of the containment fence surrounding SCP-XXXX.
Dr. ███████: Climb over the ladder onto the other side of the fence.
D-7391: Anything is better than a gray cell wall, hell yeah!
D-7391 climbs over the ladder and onto the other side of the fence, and waits.
Dr. ███████: Walk into the forest Northwest, and take breaks as you need to do supplement your thirst or hunger.
D-7391: Sure thing.
D-7391 walks Northwest into SCP-XXXX, continuing for 4.1 kilometers, stopping 3 times to consume water and 4 nutrition bars.
D-7391: Uhh, I think I found footprints.
Camera feed shows distinct footprints within the mud that are in correct correlation with Exploration I's position.
Dr. ███████: We see them over here too, please follow them.
D-7391: Um, ok.
D-7391: Is there someone else in here with me?
Dr. ███████: We cannot confirm that right now.
D-7391 walks for a total of 20.6 kilometers, stopping 11 times to consume water and 12 nutrition bars before stopping for their nighttime sleep.
D-7391: How in the world do I setup this goddamn tent? There's nothing in here to tell me.
Dr. ███████: There should be instructions at the bottom of the bag.
D-7391: Nothing, there's nothing in here.
Dr. ███████ converses with other test members and discover instructions were forgotten to be put in the bag.
Dr. ███████: Go without the tent for the night, just put down your sleeping bag on the ground.
D-7391: Am I gonna freeze to death or some shit?
Dr. ███████: You will be fine.
D-7391 removes water bottle, sleeping bag, knife, and 2 nutrition bars from backpack and lays them all on the ground. D-7391 climbs into sleeping bag.
Dr. ███████: Remove the camera from yourself and lean it against the tree closest to you, facing you.
D-7391: You wanna watch me sleep?
Dr. ███████: Yes.
D-7391 removes the camera from herself and leans it against the nearest tree facing her.
D-7391: Uh, good night?
D-7391 awakes at █:██ AM with heightened breathing and heart rate.
D-7391: [hyperventilating] What the fuck was that?
Dr. ███████: Elaborate?
D-7391: I just heard crunching of leaves, like someone was fucking running to save their lives.
Audio feeds show no sign of such sound.
Dr. ███████: We did not pick up any of that on our end.
D-7391 does not appear to sleep for the rest of the night.
An automated alarm goes off on the camera to awake D-7391 at █:██ AM.
D-7391: I'm awake, I'm awake.
Dr. ███████: Pack up all of your equipment and follow the footsteps as you did yesterday.
D-7391: I don't really know if I want to, I really don't want to. Please don't make me.
Dr. ███████: Follow the footsteps.
D-7391 packs remaining equipment into backpack and follows footsteps for another 4 kilometers, consuming 2 nutrition bars and some water along the way.
D-7391 follows the footsteps and stops suddenly.
D-7391: JESUS CHRIST! That's a massive hole!
Dr. ███████: Explain.
D-7391: Well, uh, the footsteps lead to here and there's this giant ass hole and I can't even see the bottom of it.
Footsteps are in accordance with Exploration 1's last known position.
Dr. ███████: Pour some of your water down it and count until you hear the water reach the bottom.
D-7391: Sure, I guess.
D-7391: 1, 2, 3, 4, 5, 6, 7 - 7 seconds.
Dr. ███████: Could you estimate how deep the hole is?
D-7391: Uhh, 650 meters maybe? 675?
Later analysis shows that the hole was 745 meters deep.
Dr. ███████: Are there any articles of clothing or anything unnatural surrounding it?
D-7391: Uhh, let me check.
D-7391 walks around the perimeter of the hole.
D-7391: Nothing so fa- oh wait! There's a black boot here thats - oh gross. It's covered in uh, vomit.
Dr. ███████: Is there anything else?
D-7391: No, doesn't seem like there's anything.
D-7391: [panicked] Oh no, oh no, oh no. I hear that sound again, oh no no no no.
Dr. ███████: Could you explain?
D-7391: It's that crunching of the leaves, the sounds of someone running, panicked, oh god please make it stop. It's getting louder. Oh no no no.
Audio feeds show no sign of such sound.
D-7391: [sobbing] I can't take this anymore. I don't want to do this. I just want to go home.
Dr. ███████: The sound of which you are hearing seems to not exist, there is no reason to be afraid of it.
D-7391: [sobbing] You don't know what it's like in here, you fucker. I just want to see my family, I want to see my husband. I want to see my kids grow up. All of this just because I █████ a █████? This isn't fair. I just wan-
D-7391 appears to be hit by an entity with unknown force. The audio and video feeds cease, and no attempt to reestablish connection is made.
Later analysis was not able to determine the source of the sound and the force. The source is still under investigation.
The hole discovered by D-7391 is currently not known how it formed. Analysis of soil showed that it would be near impossible for sinkholes to form, let alone one this large. It is possible that the entity that struck D-7391 caused the sinkhole.
UPDATE █/██/2019
Ethics Committee has called for a temporary halt of all testing/explorations on SCP-XXXX to find the issues with the previous explorations and better prepare for future ones with fewer loss of life.
