Leads

A summary and description of leads in System Migovec.

Alkatraz

Description Under Alkatraz is a maze of passages, which eventually break out into a small chamber with a cairn and a chocolate bar wrapper. Although there are survey stations (Tetley), they don't appear on the survey. Following the water down leads to a wide, tall streamway that cascades down over short, free climbable drops. The water disappears into a small chamber with a crack in the floor, but the rift continues onto a chamber, with a ledge a few metres off the floor. There is a poorly placed spit and no evidence that anyone has been down. The rift continues on the other side of this chamber, and seems to go. A nice high level lead, with lots of surveying to be done.

Smer 0

Description
Undescended shafts in Smer 0. Smer 0 (south) is punctuated by a couple of undescended shafts. Unknown size or depth. From Smer0, the gallery of varying dimensions is interrupted by climbs on loosely packed, flaky mud. The first rope heading into the ceiling leads to Smer1. Leads of Smer0 occur after an extensive boulder blockage. Far end of the passage is a large triple aven chamber well worth a look.

Cattle Grid

Description
Undescended pitch in Cattle Grid. Following the water beneath Knot Very Good leads to a ~6m pitch. Notes on access: alternatively, follow muddy crawl by the rope landing of Knot Very Good to access a network of mud plastered phreatic passages taking half of the water which goes to the undescended pitch in Knot Very Good. Bypasses dodgy climb.

Karstaway

Description
Before the climb down to the lunch room in Karstaway, a chamber can be entered. Downwards in this chamber seems to reconnect to Karstaway but at the back a crawl leads off. Unexplored. From chamber, low passage at the far end (NW) leads in tight rift overlooking yet another way down to the Karstaway rift, closer to water chamber.

Rhys, Tanguy

Description Between the water chamber and the first pitch of Mighty Fine Indeed are two undescended shafts. They can be reached through down climbs in the floor of the passage. One is a pitch in a wide rift, about ten metres deep. The second is a seemingly infinitely deep hading rift that needs to be bolted to be safely descended. Neither obviously connect up with the further development in Hall of the Mountain King.

What a Coincidence

Description Half-way between Hall of the Mountain King and (presumably, but as of 2016 unconfirmed) Ajdovscina there is an undescended pitch in a low chamber with a dark brown mud floor. The exploration continued over the top, following a narrow streamway upstream, but the water flows down the pitch and presumably onwards from there. There is also still the confusion about where the far end of What a Coincidence ties in, and this is effectively a lead in itself.

Povezava

Description From Sejna Soba, a little way into the Povezava branch, turn right at carbide-marked junction to the head of a clean washed, water chamber. No signs of descent from the obvious pitch head, and unmarked on the 2011 survey. Exciting!

Déjà Vu

Description From the Déjà Vu chamber below TTT pitch, follow the draught upwind to undescended 15-20m pitch. Spacious.

Knot Very Good

Description
In the Knot Very Good chamber, a climb up next to the Smer 0 south going passage could lead to a passage. When investigating a window on the other side I saw a large passage leading off here. It doesn't obviously immediately connect to Smer 0. Getting to it from above it complictaed by a concave ceiling and walls,and from below by chossy rock.

Povezava

From Sejna Soba, a little way into the Povezava branch, go straight, with the strong draught at the carbide-marked junction to the head of a downclimb into Povezava aven. On the left side of the circular aven a cleft in the wall leads up 10m to a shadowy ledge and possible on-going passage. One of the most easterly leads of the Primadona passages.

Cloaca Maxima

At the junction leading to the great aven turn left, upwind to a smaller 10m aven with possible continuation of the phreatic tube at the top. Rock of good quality, with plentiful ledges. Author(s)

Crack For Mice

Description
At the bottom of the intitial large pitch of Karstaway a small passage leads off (besided the obvious large continuation of Karstaway) At the end is a squeezey pitch-head above a ~5m drop. It has been bolted and rigged and Clare managed to get through. I (Rhys) also managed to get through briefly but then had some trouble getting back through again. Would not take much to enlarge it and the passage is large beyond and continues.

Lazarus

Description
In Miles Underground on the left wall (looking deeper into the cave) possibly marked by a huge cairn (may be a large pile of boulders now) a crawl leads off. Its kind of halfway up the wall, on a ledge, hidden behind a boulder so its not easy to spot. Through the crawl a serious of small sand filled chambers are traversed eventually popping out into a much larger passage. A rift leads off and upwards to the right. A large chamber to the left has a continuation at the top (accesible without climbing probably?).

Davey Jones' Locker

Description
Follow the streamway in Sic Semper Tyrannis downstream. Past a small perched sump. The stream drops away into a huge chamber, climb over this and find a pitch at the end of the passage. Descend into a large boulder filled chamber. A way on down into the boulders eventually brings you to a crawl which ends in a large pitch. The bottom can't be seen because of the slope of the rock. A large amount of water can be heard. Likely this is some connection with Lethe. It might enable you to bypass the sump (not sure what the blocker is really) at Lethe.

Razor

Description
Large rift at end of Guillotine/Razor in Minotaur Rift. After a fairly long crawl the passage breaks out into a large rift (30m high). Someone suggested that this probably just connects with Milky Way in some way but survey shows that at least theres some metres to be had here.

Climbs

Agatha

Description
Following the streamway from Cuckoo's Nest upstream and up a series of climbs to bypass waterfalls brings you eventually to a waterfall that no one has yet climbed up. It is probably possible though. Next people to go should probably rig the climbs with hand lines as they are a bit sketchy.

Jet Stream

Description
At the apex of Jet Stream, it is possible to climb up rather than going down. Its not that big but it appears some of the draft is going this way. Bolts for protection as the wall is quite slanted most of the way up.

Also a crawl can be free climbed to which leads to the top of a small boulder filled chamber. Would need rope to safely descend into the chamber. It is possible that this is just the top of the boulder choke that you pass to get into Final Draft so it may go nowhere.

Hoover Dam

Description
Aven climb. Right at the end of Hoover Dam Drippy sloping aven, almost free climbable. There is a place further back as well where it might be possible to climb up out of the drips and rejoin higher up.

To Infinity And Beyond

Description
Aven climb. Rift gradually slopes upwards and narrows (1 or 2m wide), filling with boulders and debris. It is possible to free climb quite high in this but it gets scary. Seems to keep going, bolts needed for protection more than climbing.

Smashed Swede

Description
Above head of Laurel, passageway can be seen departing in the distance. Stefan broke his leg here attempting it as a climb. Close to 'The Lost World' in sys-mig.

Rizla Rift

Description
From enormous jammed boulder rebelay on Laurel, rift disappears off and above. Requires protection. Noticed by Tetley, Derig 2005.

Captain Kangaroo - Traverse + Mud Slump

Description
From Traverse chamber (10m pitch after Bonus chamber), traverse round to rift that leads off. 20m later you arrive at a dodgy freeclimb into a second, sandy floored chamber. Follow the rift leading off to a pitch head (left rigged 2005). Descending a couple of metres arrives in a rift, which continues. Tight but passable.

Descending all the way (~8m from pitch head) takes you into a mud sump, obviously perched. A low crawl leads off to terminate at a wall. Possible dig.

Minestrone/Kokain Lab

Description
Two passage about 30m about pointing directly at each other. PAssage looks very similair on both sides so they likely connect. On the Kokain Lab side it seems like the continuation is in the floor somewhere and is filled with very large boulders. On the Minestrone side I think the passage gets very low (flat out crawl) and also has rocks in.

Connecting them would create a possibly much easier route to the southern extensions via Big Rock/Balamory/Kokain.

Salvation

Description
In salvation (a sandy phreatic) at some point there is a junction where one way on is completely filled with sand. Would be an easy dig (lovely sand) but no way to know for how long you'd have to dig.

We Are Not Alone

Description
We Are Not Alone leads off from Atlantis. At the end a squeeze leads into a larger chamber. I managed to pass through the squeeze and the passage continues as a bizarelly square shaped crawl with a rocky floor leading off. Small nodules of rock is the main crux of the squeeze so feather/wedges would make a big difference.

Choke A Bloke

Description
Follow big passage (Meridian Way) south. At the end is a boulder choke a way on can be seen through a squeeze. Major obstacle is one small triangle of rock. Potential for use of explosives or even feather/wedges. (Oli/Clare for more info).

Captain Kangaroo - Olympic Rift

Description
Very end of Captain K; rift becomes increasingly tight. Large echo beyond, drafting. Something very large. Rift was forced to this point with hammer + mad Polish cave diver.

Hoover Dam

Description
Just before the aven climb at the end of Hoover Dam a crawling sized tube leads into the wall sloping steeply upwards. It's possible to follow this tube for a long way before there's a sudden vertical section downwards. It was too tight to pass. maybe if you start stripping. Not so obvious the passage improves beyond but it would seem odd for it just to close down.

Slinging in the Rain

Description
In the Slinging in the rain chamber (after the first small pitch) traverse over the next pitch via the right hand wall. A crawl leads off on the other side. The way is blocked by two large boulders. Likely would need some capping but the passage continues the same on the other side and hopefully would bypass the perched sump.

Straight Jacket

Description
Tight squeeze at end of tight streamway series. Clare was put off by it. Note more for posterity than suggestions that anyone should go back.

Leki Pot

Location
Leki Pot is at the west end of NCB passage, on the north side (right as you go in), just before the last big pitch off NCB. Description

A small shitty, spiky passage leads to an 8m pitch. At the bottom the pitch, about 2m off the floor, there is a small tube, about 3m long, which breaks out into a ~25m dry pitch.

Rigging Guide
Sling round a natural for the 8m pitch. Possibly, a sling could be useful for getting into the tube. The ~25m pitch is unbolted. State of Exploration

The ~25m pitch has not been descended. On either side of the pitch there are two large windows which could lead to horizontal passages. This will require traversing round the top of the pitch (bolting). Survey details

stn leki.2 is a bolt mark at the top of the ~25m pitch.

Obelix

Location
Follow Exhibition Rd past Spirit of Elvis. Climb down large boulder climb, follow Exhibition road round to the left and the first pitch on the left is Skalar. Descend Skalar and enter rift (Dogmatix). At the end of Dogmatix is Asterix pitch head (v. tight). Go down Asterix (wet at bottom of pitch). Climb up to sandy platform at top of Obelix. Description

Obelix is a huge 80m deep shaft with a ledge about 20m below the pitch head. The first hang is dry, becoming spray-lashed below the first rebelay. At the bottom of the pitch, the water collects and runs into a small chamber (on the left as you face the open space). Then it drops drops a small pitch and disappears into a low rift passage. Up the climb at the bottom of the pitch leads to a high passage on the right (\~1.5m wide) which curves round to the left. Following this passage leads to a small pitch (Getafix) on the left. Continuing the passage straight on leads to top of undecended pitch.

Rigging Guide
- 95m rope - large sling - 6 hangers and maillons

Backup starts at a bolt in wall far from the pitch head. First hang is a Y-hang from a bolt in the left wall and a natural around a rock spur on the right. Next re-belay is bolt on the ledge 20m below. Descend c. 15m and swing left to next bolt, then a further 15m and slightly to the left to the final bolt hang. Those of a nervous dipsotion may wish to take a hammer to the scary sharp rock close to the rope immediately beneath the final bolt.

State of Exploration
The small pitch at the bottom of Obelix leads to a small rift, probably too small but might be passable after hammering. An undescended pitch exists next to survey station Obelix.12 (see above), around 25m.Getafix has an unexplored rift heading towards the bottom of the Paradiso series around 50m away. Survey details

Survey station 12 is a carbide mark next to the tag at the pitch head found by following the passage from the base of Obelix.

Getafix

Location
Getafix is found by following the passage at the base of Obelix to a opening in the left side wall immediately before a 1.5m climb up to near survey station 12.

Description
Getafix is two small pitches, the first a hang of around 5m, the next around 8m, leading to three merged chambers with an interesting pool formation, mud-marks on the otherwise clean-washed walls and small highly polished multi-coloured pebbles. Three rifts lead on from each of the three chambers (see later).

Rigging Guide
- 25m rope - 3 hangers and maillons - rope protector (not entirely necessary...)

The backup is a bolt in the wall at the opening. The rope protector can be used immediately below this. The next hang is an obvious bolt. This leads to a floor, close by is a rift opening with another bolt leading to the chambers. State of Exploration

Of the three rifts, one is too small to pass (past the pool formation), one could be hammered but shows no signs of changing size whilst the third is a rift carrying water that is large enough to enter though will require artistic rigging/bolting. The survey shows that this rift is heading towards the Paradiso series (145 Mag.) around 50m away and is as such an interesting lead.

Survey details
Station 1 is a pencilled in started bolt next to the rift lead, stations 6, 8 & 10 are the bolts from the bottom up and station 14 is Obelix station 14.

U-Bend

Description
Go in and get to the main pitch, current lead is towards Pri Madoni about 20m down into a rift. Last progress was done with bang because it got tight but before the bang I squeezed through to about my waist and saw a tube going along and down.

Hawk Cave

Description
Descend cave from single bolt belay, natural thread backup, rebelay on cleft in rock. Passages off in many directions; long phreatic (?) crawl that ends at gravel pile. Seems to be traverse + continuation round to the left from the pitch-head / rebelay ledge. Very very briefly looked at after dropping the pitch due to inclement weather...

HairDryer / East Pole region?!
Keyhole / Postcard

Description
Keyhole cave and postcard cave are very near the bivvy. The easyest way to describe them is to start from the edge of the shakehole with hare cave in. Facing towards primadoni direction hare cave is on the left side of the shake hole. Basically you are standing above postcard cave. It is in a smaller shakhole behind you. The entrance is a very low thin bedding plane that immediately breaks into an 'impressive' entrance phreatic tube with a choked draughting rift in the floor. This looks like many other entrances, so the way to confirm is that keyhole cave should also be present in the shakehole. Still facing the same way (i.e. away from the shakehole towards the hare cave shakehole), keyhole cave is on the left side and is almost completely invisible unless you are standing in exactly the right place. Entrance is a lovely phreatic keyhole about 1m high and really very hidden. The cave follows this shape for a couplle of metres before ending in a choked small chamber. Not that interesting but a great entrance - would make a supurb start to a trip.
