Note: Following the events of June 16th, 1998, Mobile Task Force Trotter-5 "Hell's Heroes" was assigned to further analysis of SCP-2951. Their assigned goals were to assess the anomalous nature of SCP-2951, as well as search for the additional three lost search and rescue crew members and Tevin Napier, who was still missing. The four-man team was to enter SCP-2951 through the secondary access shaft, and spend no longer than forty minutes within the mine.

[BEGIN LOG]

T5-1: Mics are on.

T5-4: On.

T5-2: Check.

T5-3: On here.

T5-1: Alright. Let's head down. (Pauses) Be careful right here, don't put your foot on that. It's loose.

T5-3: You guys aren't going to let us loose on our way down, are you? (Off-mic laughter, T5-3 laughs) Your paperwork to file, I mean.

T5-2: Come on Kevin, for fuck's sake.

T5-3: Alright, alright.

(T5 team descends shaft. T5-4 notes depth as they descend. Upon reaching 120m, T5-1 stops.)

T5-2: What's wrong?

T5-1: This is it. What's our depth?

T5-4: 120m.

T5-1: That ain't right. Those state guys said this was more than 200m deep.

T5-2: Maybe there's a jog? Just around that bend over there, maybe it descends some more.

T5-1: You'd think we'd see some hooks around here though, right? From the last guys.

T5-3: Nothing like that. Footprints though, so this is definitely where they were.

T5-1: Turn on your lamps, let's see what's around the corner here.

(Team detaches from tethers, moves to corner away from shaft.)

T5-1: Davies, did you start our clock?

T5-2: I did, back when we hit dirt.

T5-1: Good to hear. Let me know every ten minutes.

T5-2: Yep.

T5-4: Cap, over here. Something on the wall.

T5-3: Tether lines. From where they were rubbing up against the rock. How many are there?

T5-4: Just two.

T5-2: That's weird.

T5-1: Get some pictures, and let's keep going. We don't have a lot of time.

(Team descends lower into the mine. Extraneous dialogue removed from log.)

T5-2: Ten minutes.

T5-1: Huh.

T5-2: What?

T5-1: Feels like it's been longer than that.

T5-2: (Pauses) Clock is working fine, batteries are all juiced up and everything.

T5-1: Just imagining it.

T5-3: Man, it gets really tight up there. This is an access shaft?

T5-1: Yeah. Supposed to connect with the rest of the mine, but it's just an emergency exit. We'll have more room to breathe once we reconnect.

T5-4: We're going to need to go single file.

T5-1: I'll take the head. File in.

(Team begins to move single file through a section of tunnel. Significant time passes, but little discussion is had between team members.)

T5-1: Where are we at on the clock?

T5-2: (Pauses) 17 minutes.

T5-3: That definitely isn't right.

T5-4: Is this a temporal anomaly?

T5-1: By the looks of it. (Pauses) You guys see that?

T5-5: What?

T5-2: Light?

T5-1: Bet that's the rest of the mine. Not much further to go now.

T5-4: I hear something.

T5-3: Probably the wind.

T5-4: No, it's below us. Deep.

T5-2: Might be more seismic activity.

T5-5: That definitely isn't right.

T5-1: Let's get out of this hole, then. A cave in here and we're toast.

(Team moves quickly towards the light in front of them. Passageway begins to open slightly.)

T5-2: Why would there be light down here?

T5-4: Maybe the other rescuers? They had lamps, I think.

T5-2: Yeah, but it's been a few days. They can't be rated for that long.

T5-6: Where are we at on the clock?

T5-2: Uh… 17 minutes.

T5-3: Fuck.

T5-2: This isn't right.

T5-4: How much further?

T5-5: No, it's below us. Deep.

T5-1: Yeah, maybe another twenty meters.

T5-2: Move your asses, boys. I feel funny.

T5-3: If you're gonna throw up, keep it back—

T5-4: Shut up, man.

T5-7: Where are we at?

T5-1: 10 meters.

T5-2: It's like we're getting pinned in—

T5-5: How much further?

T5-3: Fuck!

T5-4: Where are the lights?

T5-1: Hang on. My lamp is out too.

T5-6: Fuck!

T5-2: Something is moving.

T5-5: It's below us. Deep.

T5-1: Can you all calm the fuck down for five seconds.

T5-3: Can't see in the dark, Cap.

T5-1: I've got a lighter.

(Silence. Lighter flickers on.)

T5-1: Alright. This tunnel is blocked.

T5-2: Might be from the seismic activity.

T5-4: No, it's settled. This has been here a while.

T5-1: This tunnel, though—

T5-5: No, it's—

T5-1: This looks pretty clean cut. What do you see down that way?

T5-3: Not much. It just keeps going down.

T5-2: I smell something. Ozone.

T5-1: Yeah, me too. What's our clock at?

T5-3: Something written on the wall here, I can't make it out.

T5-2: 13 minutes.

T5-1: We've been down here too long already.

T5-5: Too long.

T5-3: You want to head back?

T5-1: I'm thinking we need more equipment, maybe more—

T5-6: Too long.

T5-2: I'm fine with that. I don't want to go down there yet.

T5-4: I'll go first this time. Everybody squeeze in.

T5-7: Too long in the fire.

T5-1: Let's go.

(Time passes. Extraneous dialogue removed.)

T5-2: Thank god, I can see again.

T5-3: There's the access shaft.

T5-4: Hang on. Did you say something?

T5-3: No?

T5-4: Who— shit! What are you?

T5-2: There were only four of us, right?

T5-6: There were only four of us, right?

T5-1: Jesus fucking—

T5-7: There were only—

(Gunshot)

T5-5: Too long in the fire, too long in the fire, too long in the fire, too—

T5-1: Fucking shoot the goddamn gun Daniel, I don't care who it sounds like.

(Gunshot)

T5-6: We've been down here too long already.

(Gunshot)

T5-1: Who the fuck—

T5-3: They're wearing our uniforms, how—

T5-4: That one is smoking, it's on fi—

T5-1: Stand back!

(Violent combustion)

T5-2: What's it saying?

T5-1: Get the fuck do—

(Violent combustion. All recording devices cease function.)

[END LOG]

Note: Following these events, MTF T-5 was removed from the access shaft and given a physical and psychological evaluation. T5-1, -3, and -4 suffered minor lacerations and burns as a result of the explosion, and T5-2 was moved to Site-81 for his injuries.

The three unidentified individuals who attacked the members of MTF T-5 all wore the exact same uniforms and equipment as the other members of the unit, and were confirmed to have exactly mimicked the voices of other team members. This, combined with the low lighting and tight quarters is believed to have contributed to the team members' inability to distinguish exactly how many individuals were with them at the time.
