Its almost dead on the 1000 ft mark, see the
map, it shows that the waterhole 3 (confused that for P3 earlier on) on the map ends running into the peanut tunnel, although its not as simple as that - they dont T, its a gap off to the left through a small opening, prior to that there is a sidemount tunnel off to the pothole line on your right and another over to the W3 line on your left, cant recall distance, only that they are less than 1000ft, maybe like 5-600 and around 7-800, respectively at a guess. I believe i am getting my tunnels correctly here, but i have only gone on those lines (pothole and peanut once each) once so far - looks like you could traverse the P1 (peanut)-W3 if you have the training, skills and desire - Mike i know you have at least 2 of those.
